You know how a knit 1, purl 1 rib is nice and stretchy except for that taut line along the cast on edge? The Long Tail Tubular Cast On is designed to fix that problem! Once you try this cast on, you will appreciate how magical it is. The technique is surprisingly simple and very similar to the traditional long tail cast on, but it creates a beautiful, elastic edge, perfect for hats, socks, cuffs or anywhere you need a little give. Here’s our Long Tail Tubular Cast On tutorial to show you how we do it!

I’m going to show you how to do a long tail tubular cast on. I love this cast on for any sort of one-by-one rib. It has a really great elasticity and it really curves around the edge in a way that integrates beautifully with the fabric. I’m also going to show you how to modify it for a two-by-two rib. So let’s get started. 

I’m going to start with a slip knot and a needle. We have our first stitch. Here we go. So I’m gonna orient my hands how you would for a basic long tail cast on. I have my tail in front. I have my working yarn in back. I’m gonna take these two fingers. I’m gonna split them. I’m gonna take these three fingers and grab the yarn below. And I’m gonna just pull back slightly. So I have this kind of slingshot kind of action going. 

I’ll show you how to do that one more time. So Divide the two, grab the yarn below with your three other fingers, and then pull back slightly. So as I said, this slip knot here, this is going to act as our first stitch. And now, I’ll show you how to do the cast on, which creates kind of a purl knit, purl knit appearance.

So, first, we’re going to start by taking the right needle under the yarn coming from the index finger, and then under the yarn coming from the thumb and then once again under that index finger yarn. So there’s our first stitch. You can see as this yarn in front of it right here almost looks like a pearl. That’s just what we’re looking for. 

So now let’s make a knit stitch. We’re going to start by going the other way first. So take your needle to your thumb and go under the yarn coming from your thumb. Take the finger to the, your needle to the thing, your finger and go under that yarn and then under the thumb yarn again as well.

So here you can see we’ve created another stitch and it looks kind of like a knit stitch. So let’s keep alternating going first to the finger and then to the thumb. So under the index finger yarn, under the thumb yarn and under the index finger yarn again. So this time we’re going to start going the other way under the thumb yarn, under the index finger yarn and under the thumb yarn again.

There we go. Index finger and under thumb, under both of them. So we’re going to go to the thumb, go under the index finger. Go under both of them. Here we go. So we have two, four, 6, 7. We’ll go to 12. You can see this, the last one we did was a knit stitch. So to do a purl stitch, you start by going to the finger, go under, go to the thumb, go under both of them.

Finger, thumb, finger, under both of them.

I’ve lost count again. Here we go. 2, 4, 6, 8, 10. Do two more. Go under the thumb, go under the finger, both of them… finger, go under the thumb yarn, go under both of them. Alright. So now we’ve got 12 stitches here. If you take a look, you can kind of see how every other one looks like it’s a little, has a little purl bump, including the last one.

Now I’m going to turn my needle to work the first of two foundation rows. And when I do that, I’m going to kind of just, hold this tail against the needle, just to keep everything secured. Because the last stitch is going to want to be a little bit loose on you. So just try to secure it by holding down this tail.

So when you turn the needle, you’ll see that the stitches that were purls on this side now look like knit stitches on this side, but the leg is in the wrong place. So across this whole row, we’re going to work into the knit stitches, but through the back loop instead of the front loop. And that’s to get them oriented correctly.

So the first one is a knit stitch. We’re going to knit through the back loop. Now for the purl stitches we come across, we’re going to slip them with the yarn in front. So we’re going to slip this stitch with the yarn in front. I’m going to take my yarn to the back in order to knit this stitch once again through the back loop.

So, slipping the purls with yarn in front and knitting the knit stitches through the back loop. You do this all the way across the row.

Slip with yarn in front, knit through the back loop. Bring your yarn to the front, slip, knit through the back loop. Now we’re going to slip this last one with the yarn in front. So now, that first foundation row, we got all the knit stitches oriented the correct way. So, on this row, you can just knit into the knit stitches as you normally would.

And once again, we’ll slip the purl stitches with the yarn in front. Here we go. This is foundation row two. Knit and slip. So we have completed our two foundation rows. And now, if you take a look, you can see this rib has already started to take shape. We have a, you know, knit stitch and a purl stitch and a knit stitch. What looks kind of like a purl stitch. And if you look on the other side, it looks the same way. It’s a beautiful, what’s going to be a beautiful one-by-one rib.

And it has this really smooth edge along the bottom, and with a lot of elasticity in there, which is really great. So now, if you want to stick with a 1×1, you just continue, you know, as pattern instructs, or connect to work in the round, or you know, however your pattern tells you to go on, but you’re ready to work in any sort of one-by-one rib.

But, if you wanted to change this into a two-by-two rib, you’re going to do one more foundation row. So I’m going to show you how to do that right now. Alright, so here we are. Our first stitch is a knit stitch, so I’m going to just knit that normally. And of course, for a two by two rib, that means I’m going to want to knit the next stitch as well.

So what I’m going to do is I’m going to insert my needle into this knit stitch.

I’m going to knit it as normally, and then when I pull it off, it’s going to shoot this purl stitch off the needle, and I’m going to catch it with my index finger, kind of securing it, and just stick my needle right back through it. I can show you a different way to do that too, if that seems a little scary.

So now I have, oh let me show you, now I have two purl stitches next to each other, so I’m going to purl both of those. See, and our two by two rib is starting to take shape. So now I have a knit stitch, I’m going to knit it, But now I want to knit another knit stitch, but what’s next is a purl stitch. So you can, you can either go ahead and knit that next stitch, or if you want to rearrange the stitches first you can do that.

You can just let them both flop off, get that purl stitch on there first, then get that knit stitch on there, and now they’re arranged for a two by two. So I’m going to knit that one, now we have our two purl stitches next to each other, and I’m going to purl these two. Once again, I have a knit stitch, so it’s great.

Knit this one. I want another knit stitch, but I have a purl stitch in the way. So I’m going to just let those fall off. Put the purl stitch back on that left needle first then put the knit stitch on that needle. And now you’re ready to knit your second one. And then, now we have two purls at the end of our row.

making for a great two-by-two rib here that’s going to take place. So that’s the long tail tubular cast on. It’s very versatile. It’s very elastic. It’s great for ribs. I hope that helps.


LONG TAIL TUBULAR CAST ON: STEP-BY-STEP

Note

If you are an especially tight knitter, try the Long Tail Tubular Cast On using a needle 1 or 2 sizes larger than the needle you will use for the ribbing. Test your tension out on a gauge swatch to see what’s right for you!

SETTING UP

Long Tail Tubular Cast On | Purl Soho

The Long Tail Tubular Cast On begins exactly like a regular Long Tail Cast On: Pull a length of yarn 3 or 4 times the width of what you will knit. Tie a slipknot. Thread the slipknot onto the needle. Holding the needle in your right hand, grasp the yarn and the tail with your left hand, exactly as you would for a Long Tail Cast On.

CASTING ON A PURL STITCH WITH A LONG TAIL TUBULAR CAST ON

Usually, the first cast-on stitch is a purl stitch. Here’s how to work one…

From back to front in a towards-you motion, dip the needle under the yarn coming off your left index finger.

From front to back in an away-from-you motion, grab the yarn coming off your thumb, then pass the needle under the yarn coming off your index finger.

Gently pull to take up the slack. You can tell you’ve cast on a purl stitch because of the small bump below the stitch.

CASTING ON A KNIT STITCH WITH A LONG TAIL TUBULAR CAST ON

Now you will learn to make a knit stitch.

Gently pull to take up the slack. The stitch you just cast on is a knit stitch. You can tell it is a knit stitch because it doesn’t have a bump below it.

CONTINUE CASTING ON WITH THE LONG TAIL TUBULAR CAST ON

Repeat the Long Tail Tubular Cast On steps, making alternating purl and knit stitches, until you have cast on the correct number of stitches. Some patterns might ask you to start with a knit stitch after the slip knot, but most will start with a purl as shown above. And remember, as with any cast on, the slip stitch is the first stitch of your cast-on row.

When you’ve cast on the required number of stitches, twist the tail around the working yarn once or twice and go on to the foundation rows.

FOUNDATION ROWS

Now you will work two foundation rows. Whether you’re making a hat in the round or a flat scarf, these two foundation rows are always worked flat. Find the foundation rows below that apply to your pattern.

CONTINUE TO PATTERN

Long Tail Tubular Cast On | Purl Soho

Your Long Tail Tubular Cast On is complete! Some patterns may have you work a third foundation row to set up for 2×2 rib or something more complicated. In most cases, you’ll be ready to continue to the rest of your pattern by following one of the two instructions below.

LONG TAIL TUBULAR CAST ON FOR WORKING IN THE ROUND

Without turning the work, transfer all stitches to the circular needles you will use for the ribbing. With the working needle in your right hand, place a marker on the right needle and join to work in the round, being careful not to twist the stitches.

IF WORKING FLAT

Turn the work and continue to work in regular 1×1 rib.

FINISHING

When you weave in the ends, use the cast-on tail to sew together the two sides of the Long Tail Tubular Cast On edge.
