Blueprint Blanket
Inspired by the quiet logic of architectural design, our beginner-friendly Blueprint Blanket pattern takes shape in engaging knit-and-purl stitch patterns, culminating in a grid of orderly, geometric forms. Knitting Yarn DK On A Cone—a generous 1,000 grams of gorgeous New Zealand merino wool—gives the blanket a strong, classic foundation and a soft, inviting feel.
Every stitch pattern in the Blueprint Blanket is created from knitting’s most essential building blocks—fields of stockinette, reverse stockinette, garter stitch, and seed stitch—each fitting together like a well-drawn schematic. What a rewarding exploration of the power of knits and purls!
With its round 4-ply spin and cushiony light-worsted weight, Knitting Yarn DK gives your Blueprint Blanket clear stitch definition and a bold architectural presence. You only need one Knitting Yarn DK On A Cone to knit the blanket, which means 2,187 yards of satisfying knitting to look forward to, with no skeins to wind and only two ends to weave in when you’re finished.
We knit our Blueprint Blanket in Spring Sky, a gentle blue whose luminosity highlights the pattern’s stitchwork. But like any good plan, this design is meant to be interpreted, so choose from any of Knitting Yarn DK On A Cone’s 37 fascinating colors to make it your own.
The Blueprint Blanket is a real pleasure to knit, a thoughtful design built stitch by stitch and block by block. Pick up a cone of Knitting Yarn DK and cast on for a knitting experience that celebrates care, craft, and beautiful materials.

Love this, my hobby is knitting it’s something my mother taught me
Hi Isabelle,
We’re so glad that our new Blueprint Blanket caught your eye, and we’re so glad your mother taught you to knit!
Warmly,
Andrea
Is there a pattern to make it crochet?
Hi Olga!
Thank you for writing in! At this time, the Blueprint Blanket is only available as a knit pattern, and we don’t have a crochet version. We really appreciate your interest, though!
Warmly,
Megan
Very beautiful afghan that looks like it would be interesting to knit. If you wanted to make it 60” wide and 70” long, how would I adjust the pattern?
Hi Fran!
Thank you so much for writing in! Unfortunately, Blueprint doesn’t have a repeating stitch pattern. Each block is placed individually to create the overall design. Because of that, resizing would require rearranging the blocks in each section rather than adjusting a simple repeat.
Warmly,
Megan
Can the Blueprint Blanket be modified to make a shawl? If so would you share the stitch count calculations?
Hi Margaret!
Thanks so much for writing in. Unfortunately, the Blueprint pattern doesn’t have a repeating stitch pattern. Each block is placed individually to create the overall design. Because of that, resizing isn’t straightforward and would require rearranging the blocks in each section.
Warmly,
Megan
Is the pattern reversible?
Hi Mindy,
We’re so glad our new Blueprint Blanket has caught your eye! The pattern is not the same on each side, but there is a lot of visual interest on both sides of the blanket and looks beautiful on both sides.
I hope this helps! Please let us know if you have any other questions!
Warmly,
Andrea
What an interesting pattern to knit. Thank you. My question: Is the cast on edge the 45” side or the 53.5 side?
Hi Angela,
We love that Hiromi was able to create so much visual interest with just knits and purls! The cast on edge is the 45″ side. If you look at the photo with the blanket held up, the blanket is knit from the bottom edge up.
I hope this helps! Please let us know if you have any other questions!
Warmly,
Andrea
I’d like the Blueprint pattern
I’ll buy the yarn in the green I can’t save or print

I hope this helps! Please let us know if you have any other questions!

Love love love the pattern! Is it possible to substitute the Cotton on the Cone for this? I live one the Southwest desert and a cotton blanket would be more practical.
Hi Joanne,
Thanks so much for your question!
Cotton Pure is a great option for this blanket! Because Cotton Pure is a little bit thinner and a different fiber, we recommend knitting and blocking a swatch to make sure you are able to make gauge and you like the look and feel of the final fabric. You may prefer the fabric that is made with smaller needles and has a tighter gauge. If that is the case, you’ll have a smaller finished blanket.
I hope this helps! Please let us know if you have any other questions!
Warmly,
Andrea
I purchased Purl Soho Cotton Pure On A Cone a few months back for a different project but love this pattern – is this a suitable yarn to use for this blanket?
Hi Beth!
Thank you for writing in! Yes, you can absolutely use Cotton Pure for this blanket. Since Cotton Pure is a sport weight and the pattern is written for Knitting Yarn DK, you’ll just want to knit a gauge swatch and adjust your needle size as needed. The good news is that with Cotton Pure on a cone, you’ll definitely have plenty of yarn for the project.
Happy knitting!
Megan
Thank you for sharing the beautiful pattern ! Wondering if I can make this with 10 skeins of Good wool-any change in size?
Hi Utako,
We’re so glad our new Blueprint Blanket has caught your eye!
Good Wool would be a great choice for this blanket. Good Wool is a bit loftier than Knitting Yarn DK, so we recommend knitting and blocking a swatch to make sure you are able to meet gauge and you like the look and feel of the final fabric. As long as the gauge is the same as the gauge in the pattern, you’ll see no change in the final size!
Please let us know if you have any other questions!
Warmly,
Andrea
What color is the blanket in the photo of this pattern? I’d like to get a cone of it.
Hi Antonia,
We’re so glad you love the Blueprint Blanket! We used the color Spring Sky for our sample.
Please let us know if you have any other questions!
Warmly,
Andrea
I would knit it in my favorite color..pastels of mauve..
Purple
Hi Olive!
This blanket would look gorgeous in Lavender Fog or Chive Blossom! Please send us a photo if you make it! We’d love to see!
Warmly,
Andrea
