Embossed Triangles Blanket
Remember when you learned to knit and then to purl and then you thought, “Okay, what next?” And someone told you that’s it, those are all the stitches. Wait, what?

Yes, quite a marvel, and exactly why we love a project like our Embossed Triangles Blanket, which demonstrates with ruthless efficiency exactly what two little stitches can do.

Knit-side triangles flicker past purl-side ones, forming squares that tumble across the entire face of the blanket. Despite the rigorous geometry here, our minds turn to nature and her awe-inspiring math skills: pine cones and gemstones, fish scales and feathered friends.

You’ll need just one Cotton Pure On A Cone to make this entire blanket. One hundred percent organically grown cotton, this yarn is incredibly soft and supple, simple and classic, and it, plus some knits and purls, make one heck of a beautiful blanket!

Materials

- 1 Cotton Pure on a Cone, 100% organically grown cotton. Each cone is 2789 yards; approximately 2588 yards required. We used Heirloom White. (Prefer skeins? You’ll need 10 Cotton Pure skeins!)
- US 3 (3.25 mm), 32- or 40-inch circular needles
- Stitch markers (optional)
Gauge
24 stitches and 36 rows = 4 inches in stitch pattern
Size
Finished Dimensions: 42½ inches wide x 57 inches long
Note
Slipped Stitches
Slip all slipped stitches purlwise with yarn in front.
Stitch Multiple
This pattern works over a multiple of 21 + 4 stitches
Stitch Markers (Optional)
For Rows 3-22 of this pattern, you will repeat 21 stitches 12 times. You may find it helpful to use stitch markers to indicate the end of each repeat. To do this, the first time you work Row 3, place a stitch marker after the first two slip stitches, then one at the end of each [p20, k1]. You will place 13 stitch markers.

I am considering using the Sweetgrass on 3s for this pattern. Do you recommend that as an acceptable substitute?
Thanks!
Hi Chermia
Thanks for writing in! This would be beautiful in Sweetgrass.
Since Sweetgrass is a fingering weight yarn, I would recommend knitting a gauge swatch in pattern first. You can then measure your stitches per inch, multiply that number by 42.5 inches, and round to the nearest multiple of 21 plus 4 stitches to determine how many stitches to cast on. Hope this helps!
Happy knitting
Jessica
Hello – Does using the cone have breaking points or is it one long continuous piece. Like some of the colors that are currently sold out in the cones but are available as skeins – but not having to weave it ends is appealing!
Thanks,
Christina
Hi Christina,
Thanks for writing in! Yes, the advantage of the cones is that you won’t have to weave in nearly as many ends – just the ones from casting on and casting off! If you would rather wait for the cone, you can enter your email address on the product page for the colors you are interested in and we will email you as soon as they are back in stock.
Best,
Julianna
This is such a beautiful pattern with a lot of texture and interest. I am in the middle of my gauge swatch and find this pattern a real pleasure to knit.
Not too difficult to keep track of the changes, very satisfying to see the embossed triangles forming: a great project. Love the I-cord on the edges, too. Thank you!
I’m making this as a baby blanket. Could you please give me the dimensions for that blanket. Thank you very much!
Nancy Rylicki
Hi Nancy,
Thanks for writing in! A typical baby or crib blanket measures about 30″ wide by 40″ long. To make this blanket 30″ wide, you will need to cast on 172 stitches.
Happy knitting!
Julianna
Hi –
I read in a previous post that in order to make this as a baby blanket, cast on 172 stitches. Will the number of stitches per row in the pattern remain as written? And, will there be 15 repeats of the 22-row pattern. Thanks!
Hi Julie,
Thanks for writing in! This blanket will always have the exact same number of stitches you started with at the end of every row, so if you cast on 172 stitches, you will always have 172 stitches on the needles. For the smaller crib size, you will continue repeating the 22-row pattern until the blanket measures about 40 inches long, which should be roughly 16 or 17 repeats.
Happy knitting!
Julianna3
Thanks for your reply, Julianna!
I understand the number of stitches will remain the same for each row, but will each row be followed as it’s written in the pattern? For example, Row 3 says: “slip 2, *p20, k1, repeat from * to last 2 stitches, slip 2”. So, will I follow it as written for the baby sized blanket? Sorry for my continued confusion.
Hi Julie,
No problem, I’m happy to clarify this! You will knit every row exactly like our pattern! This smaller size has already taken the stitch multiple into account, so you will be able to knit it as written.
Best,
Julianna
Hi. Why do you cast on 256 not 277 (which would be 21 x13 + 4)? I need to make a crib size not throw size, so trying to size it down, but that 256 doesn’t make sense as i can’t see any increases – what am I missing, I wonder? I was hoping that for crib size, 7 repeats would be about right, so should I cast on 21 x 7 +4? Thanks
Hi and thanks for getting in touch! You are absolutely correct, there will be only 12 repeats of the pattern – although you will still need 13 stitch markers! This line in the notes has now been corrected. 7 repeats, or a total cast on of 151 stitches, will result in a 25-inch wide blanket, which will be perfect for a car or stroller blanket!
I hope that helps, and thank you so much for pointing out our error!
Julianna
I was looking to make this into a baby blanket and was wondering how to do that! Thanks in advance! PS, I know someone had asked this in the comments previously because I saw it when I ordered the yarn, but now I went back and can’t see any of the comments!
Hi Samantha,
Thank you so much for getting in touch, and I apologize that our comments aren’t available at the moment! We are experiencing a few technical difficulties with our site right now, but our web team is hard at work to get everything restored as quickly as possible. The comments should be back in the next day or two! For a typical baby or crib blanket measuring about 30″ wide by 40″ long, you will need to cast on 172 stitches and you will need 5 skeins of Cotton Pure.
I hope that helps, and happy knitting!
Julianna
Hi. I am over halfway finished with this lovely blanket. The pattern is a pleasure and the recommended yarn is lovely to stitch with. Do you recommend blocking this blanket? If so, what temp should the water be?
Hi Sandy,
We’re so happy to hear that you’re enjoying knitting this pattern! It’s not required to block this blanket, but blocking will bring out the best of the cotton yarn and reduce the curling edges of the fabric a bit! If you’d like to block this blanket, you can use cold water to do so. I hope this helps!
All the best,
Cat
Hi, I just finished first repetition of rectangle. The pattern says to start again with row 1 but I can’t see this on the pictures. Shouldn’t the repetition be rows 3 to 22? Thanks in advance.
Hi Pak,
Thanks for reaching out! You repeat starting at row 1-22 until piece measures 57 inches, ending with Row 1 again!
Hope this helps, happy knitting!
Gianna
Hi There! I’m thinking that this might be a fun pattern to knit in a variety of colors. Does each 22 row pattern repeat result in a row of squares (formed by the two triangles)?
Thank you!
Hi Barbara,
Thanks for writing in! I think this pattern in a variety of patterns would be so fun! Yes, after completing rows 1-22 you will have a for of squares formed by two triangles!
All the best,
Gianna
Thank you, Gianna!
Thanks for the great patterns and yarns! I’m currently working on the cumulus wrap and the sideways garter vest.
For this one, I was thinking of using the Good Wool instead of cotton. What needle size would you recommend? Thanks again!
Hi Monica,
Thanks for reaching out and for your kind words! I am so pleased to hear that you are enjoying our patterns and yarn! Good Wool would be a great yarn for this pattern, I think the look will be beautiful! Luckily Cotton Pure and Good Wool are both sport weight yarns so the US 3 needle we recommend in the pattern should work! I do recommend working up a gauge swatch before beginning to insure that your gauge is consistent with the pattern!
Pleas let us know how this works out!
All the best,
Gianna
Thanks! I’ve ordered the wool now, so I’m excited to see how it turns out.
I would love to make this blanket, but I am a subway knitter. That makes it pretty prohibitive to make such a large object. Any suggestions on ways to break it up into smaller sections that would be easy to stitch together later?
Hi Deborah,
Thanks for reaching out! I would recommend breaking it up in sections of 2 or 3 repeats of row 1-22!
I hope this helps and feel free to reach out with any more questions going forward!
All the best,
Gianna
Does this blanket require blocking? Thanks in advance.
Hi Elle,
Thanks for reaching out! It is not required to block this blanket but I would recommend blocking to get the best effect from the cotton!
All the best,
Gianna
Hello! I understand that you should block the blanket. Does that take away the curl at the bottom? Is there a way to knit at the start to not make it curl? I am giving it away and can’t be sure the people I give it to have the time to block it when they wash it.
Thank you for a great pattern!
All the best
Nina
Hi Nina,
Thanks for reaching out! Blocking will minimize the curl, but it won’t remove it completely. If you want to make sure the edges (both the top, bottom, and sides) don’t curl at all, I’d recommend knitting a few rows of garter stitch at the beginning, end, and a few stitches on each side. The garter stitch will prevent any curling from happening, even without blocking!
All the best,
Lili
Thank you so much! I will try that.
Have a nice weekend!
Hi there – what cast on method would be best for this blanket? Thanks very much in advance.
Hi Jyoonie,
Thanks for reaching out! I recommend a basic Long Tail Cast On for this blanket!
Warmly,
Gianna
I have approximately 2,400 yards of worsted wool and was thinking of making this blanket. Do you think it could work and if so how many stitches should I cast on and what size needles should I use?
Thank you in advance
Martine
Hi Martine,
Thanks for reaching out! That should be a good amount for a blanket but based on the dimensions you are shooting for you may end up using more or less! I recommend starting off by working a gauge swatch with the worsted yarn and a US 7 or 8 needle. Based on the gauge you can calculate your cast on! I also recommend checking out our All About Gauge tutorial, it is an excellent resource to use!
I hope this helps, let me know if you have any more questions!
Warmly,
Gianna
I want to make the embossed triangle blanket in the crib size using the campo yarn. How many skeins should I purchase??
Hi Julia,
Thanks for reaching out! I would recommend approximately 12 skeins of Campo. Keep in mind that Campo is a worsted weight and Cotton Pure is a sport weight so you will need to make some adjustments to the pattern! I would recommend working a gauge swatch on a appropriate size needle (US 7-9) to calculate your cast on amount. Be sure to keep in mind that the pattern works over a multiple of 21 + 4 stitches!
I hope this helps, happy knitting!
Gianna
Are rows 12 and 13 supposed to be the same except for the beginning. Both are p10 knit 11
Hi Laurie,
Thanks for reaching out! Rows 12 and 13 are similar but are not the same, for row 12 you are: K2, *p10, k11, repeat from * to last 2 stitches, k2. For row 13 you are: Slip 2, *p10, k11, repeat from * to last 2 stitches, slip 2.
I hope this clears things up!
Warmly,
Gianna
Hi would you recommend cotton pure for a baby blanket (crib) , is it soft? and if so how would you adjust the pattern?
Hi Denise,
Thanks for reaching out! Cotton Pure is an excellent choice for a baby blanket! It is very soft and the care is very easy (machine wash cold, tumble dry low.) This pattern works over a multiple of 21 + 4 stitches so if your gauge is consistent, I would suggest casting on either 151 stitches (21 x 7 = 147 + 4) or 172 stitches (21 x 8 = 168 + 4) for a 28-30″ wide blanket!
I hope this helps, happy knitting!
Gianna
Thanks Gianna
Hi
I was wondering if you think this would work is worsted twist. Or something else light that won’t pill a lot ( not my words) in a baby blanket.
Hi Denise,
Thanks for reaching out! Worsted Twist could work if you want to re-gauge the pattern a bit! However, soft wool fibers like the fine merino that we use in Worsted Twist will pill and fluff over times. If you want to avoid that I would suggest sticking with Cotton Pure like we used in this pattern, it is a great choice for babies and I haven’t heard of anyone experiencing pilling with it.
Alternative, another great option I would recommend is one of our newer yarns Morning! It is a bit heavier than Cotton Pure so you would need to make a few adjustments but it is an absolutely lovely yarn, another excellent choice for baby blankets! It is a blend of 75% organically grown cotton and 25% yak so it is also machine washable and super soft. I also haven’t heard of any pilling issues with this yarn!
I hope this helps and please let me know if you have any more questions!
Warmly,
Gianna
Thanks Gianna I am going to check out Morning
Can I knit this in wool instead and what ply would be okay . Do I use a 4 ply wool or 8 ply . Thank you . Love this
Hi Laurie,
Thanks for reaching out! I think this blanket would be great in wool! This pattern is written for a Sport Weight yarn which is the equivalent to a 4 ply!
I hope this helps, happy knitting!
Gianna
Hi, I don’t much like a rolling edge. Would a garter border at the beginning and edge of each row prevent the roll that can be seen in your images? How do you think it would look on this lovely pattern, say six or seven garter stitches on each edge. If I was to do this, would I delete the slip 2/knit 2 part of each row? Thanks in advance.
Hi Julie,
Thanks for writing in! To get the flat edges like we have in the photos you will simply need to block the blanket when you are finished knitting! This pattern shouldn’t roll too much, but if you do experience a lot of rolling blocking will fix that, and that way you wont need to make any adjustments to the pattern since this stitch patter only works over a multiple of 21 + 4 stitches.
I hope this helps, happy knitting!
Gianna
can this be made in cashmere?
Hi Caroline,
Thanks for reaching out! You can absolutely make this blanket using cashmere! It was originally designed for sport-weight yarn, so you can use any yarn that meets the gauge called for in the pattern. Or, if you wanted to use a different weight yarn, you could adjust the size of the blanket to meet your needs! This pattern works over a multiple of 21 + 4 stitches, so once you determine the gauge of the yarn you want to work with, you can use that to figure out what size you want the blanket to be and adjust the number of stitches cast on to accommodate that.
I hope this helps, and please let us know if you have any other questions!
Warmly,
Kelsey
I have ordered 2 colors of Santolina to make a baby blanket. I plan to knit using 2 strands together which I think will be similar to using a worsted weight yarn. Or maybe closer to DK? Do you have a recommendation for the number of stitches to cast on?
Also, in order to prevent curling edges, can you add garter or seed stitches at the beginning and end of each of the rows in the 1-22 row pattern (as well as garter or seed rows at the top & bottom of the blanket)? I know you mentioned blocking would flatten any curling, but since this is a baby blanket it will be washed & dried frequently & it’s doubtful that a mom will want to block the blanket every time instead of tossing it into the dryer.
Thanks very much,
Deb
Hi Deb,
Thanks for reaching out! I would suggest starting off by working a gauge swatch with the yarn doubled and compare that to the gauge of the pattern. This blanket is originally made with Cotton Pure, a sport weight yarn so you will likely need to reduce the cast on amount, but you can determine that based on your swatch! Also, due to the construction of this blanket, I would not recommend adding a border because it will make the process much more complicated. However, also because of this construction and the triangles there is not much curling if any with this blanket, so normal washing and drying should be just fine to care for this blanket.
I hope this clears things up!
Gianna
Hello,
I would like to make this as a 30×40 inch baby blanket using Santolina. Please advise how many skeins are needed. Thank you!
Sue
Hi Sue,
Thanks for reaching out! Based on the yardage requirements for the Elementary Wrap in Santolina (which is a bit more square footage than your blanket would be), I’d estimate that you could make a 30″ x 40″ baby blanket using approximately 4 skeins of Santolina. You could always buy an extra skein just to be safe, and if you don’t end up needing it you can always return it as long as it’s in its original condition!
I do want to mention that you’ll likely need to adjust your needle size a bit for this pattern if you use Santolina; the pattern was designed for Cotton Pure, which is a thicker, sport weight yarn. I’d recommend working up a gauge swatch in pattern first, to ensure that you’re using the appropriate needle size for the thinner yarn. I hope this helps you with your project planning!
Warmly,
Kelsey
Thank you, Kelsey!
I am loving the cotton pure on a cone while making the embossed triangles baby blanket. Could you/would you recommend some type of fringe??
Hi Lucy,
Thanks for reaching out. I think that a crochet border would look great on this blanket! Or perhaps an applied i-cord edge. Hope this helps.
All the best,
Lili
I have just started this blanket and I’m somewhat of a beginner. The working yarn keeps getting very twisted and bunching up and I’m not sure why. I’ve never used cotton yarn or yarn on a cone. What am I doing wrong? Is there a way to fix it?
Hi Emily,
Thanks for writing in! Cotton yarn and other plant fibers are prone to twisting, so it is common to experience some twisting while working. It can help to massage the yarn between your thumb and pointer finger, this will resolve some of the twists. However, if you are experiencing excessive twisting, please send our customer service team photos of the yarn twists, as well as the cones lot number to customerservice@purlsoho.com
I hope this helps, happy knitting!
Gianna
Hello! I am in love with this pattern and while I would love to use the Cotton Pure on a Cone, I’m looking more for a mustard yellow. My living room is gray, deep gray blues, and mustard/gold seems to go best with that. Since I can’t see the yarns in person, is there an alternative you would suggest?
Thank you!
Hi Lindsay,
Thanks for reaching out. I think that a mustard yellow color would go wonderfully with the gray-blue hues of your living room! I would recommend Good Wool in Hay Field. Also, if you want to check to see if this color works before purchasing enough yarn for a blanket, I wanted to let you know that we have color cards for Good Wool! These would be a great option to see the colors in person. Hope this helps!
All the best,
Lili
Hello,
I love this pattern would like to adjust to make a baby blanky. Do you have any suggestions as to how I can alter the pattern so that it will make an end size of approximately 14″ x 14″?
Can you also please recommend amount of yarn? I like the muted violet colors of linen quill (peach stone), cotton pure (wild lavender) or understory (violet gray). I’m open to your suggestions of which yarn type would work well for this pattern, bonus if we can find one that has a similar color story to the examples listed above!
Thank you,
Maggie
Hi Maggie,
Thanks for reaching out! You can absolutely make this blanket pattern with the dimensions of 14″ x 14″. All you’ll need to do is adjust the number of stitches you cast on. To figure out your cast-on number, you will want to first knit a gauge swatch in pattern. Once you know how many stitches you are getting per inch, you can multiply that number by the width that you would like and cast on the nearest multiple of 21 + 4. From this point, you can follow the pattern exactly as written, though you’ll need to bind off once you reach 14″, instead of the full length!
I think that Cotton Pure would be the best choice for this pattern, mainly because it’s good for baby blankets since you can put it in the washer and dryer! But if you’re not concerned about that, then any of the three yarns would also work. Just be sure to swatch before adjusting your cast-on, because each yarn will likely come to a different gauge. And you’ll likely only need 1 skein of any of these yarns, but I’d recommend ordering 2 just to be on the safe side (you can always return any unwound and unused skeins for store credit). I hope this helps!
All the best,
Lili
I tend to knit a little tight. Do you think using size 4 needles would work or should I stick to size 3 and just try to relax a little?
Hi Kathleen,
Thanks for reaching out. Knitting a gauge swatch (or swatches) is the best way to determine which needles to use! If this is daunting, I’d recommend checking out a tutorial called All About Gauge, which covers some incredibly helpful information. I even learned some interesting, new tidbits myself while looking over it, and you may, too!
All the best,
Lili
Any suggestions for making this pattern as a baby blanket in Morning? I love the colors, and the fact that it is machine washable. Particularly, how many skeins, and what size needles? TIA for your advice.
Hi Angela!
Thank you for your question! While you certainly could make this blanket in Morning, it will be a larger blanket since Morning is a heavier weight yarn than Cotton Pure. Since a larger blanket can sometimes be quite cozy, I would suggest using a US size 5 or 6 needle with 13-14 skeins of Morning! I would also recommend making a gauge swatch with Morning to see how many stitches you are getting per inch, in case you need to adjust your cast on amount to a smaller number.
I hope this helps with your project planning!
All the best,
Margaret
Hi. How can I make this blanket in alternating black and white squares. Where wld I change color? Thanks
Hi Leslie!
Thank you for your question! This blanket in black and white squares would be so fun! After completing rows 1-22 you will have a row of squares, so one idea to create a striped blanket with alternating stripes of black and white squares. If you wanted each individual square to be a different color, that would require some stranded colorwork knitting techniques, creating a wrong side with many floats. This is definitely do-able, though! I would suggest switching colors at each stitch marker every 21 stitches (see the stitch markers note for reference!), and carrying one color of yarn along the back of the work when you are working with the other color.
We also have the Optic Blanket, the Fair and Square Blanket, and the Mitered Corner Blanket, which might be easier ways to achieve the same look without having to use any stranded colorwork techniques!
I hope this helps with your project planning!
All the best,
Margaret
Thanks! I am so impressed with your turnaround time and complete and complete and helpful answers! I’m going with the mitered sq. Blanket and have a short Q about that one too.
You are very welcome, Leslie, and thank you so much! Please feel free to let me know your question about the Mitered Corner Blanket on the pattern page, and we are happy to answer any other questions you have!
All the best,
Margaret
pouvez vous m explique les deux mailles glissées en début de rang ? Est ce deux mailles lisières ?
Hi Veronique,
Thanks for reaching out! Yes, you’re correct. The 2 slipped stitches at each edge form a small i-cord selvedge. Hope this helps!
All the best,
Lili
I know this has been asked before. I would like to make this pattern into a throw. How much yarn will I need, and how many stitches do I cast on.
Thanks
Hi Nanette,
Thanks for reaching out. The dimensions of this blanket are 42½ inches wide x 57 inches long, which is a typical throw blanket size! Are you hoping to make it larger or smaller? If you can let me know what dimensions you want to knit it to, I can help calculate yardage and stitch count.
All the best,
Lili
I have made one small project with my cotton pure cone, so definitely don’t have enough left to make the full size of this pattern! I would still like to make a throw size blanket, how can I adapt this patter so I can make it a bit smaller and knit until I run out of yarn? Should I do less repeats, or cast on fewer stitches? thanks!
Hi Winnie,
Thanks for reaching out! I would do a combination of both so that the blanket remains proportional in terms of the length and width. This pattern works over a multiple of 21 + 4 stitches, so you can cast on a number that works for that (but that’s smaller than the original cast-on), and then knit until the blanket is the length you want!
All the best,
Lili
My yarn is loose at the transition points between the squares but the yarn looks tight and even in the pictures—the look I would like. Will the yarn tighten and even out after it is washed and dried?
Hi Lisa,
I’m sorry to hear that your project doesn’t look quite like the photos of our sample! Would you be able to send a photo of your work so far to customerservice@purlsoho.com? Then we can better visualize what’s going on!
All the best,
Lili
