Whenever you make a “bottom-up” sweater “in the round” there will come a moment where you have to add the sleeves to the body. For first-time in-the-round sweater knitters, this moment is always daunting! “You want me to put what stitches where and knit them with which needles?” Our Joining Sleeves To Body Tutorial is here to help you wrap your brain around the magic. It shows you how to join the sleeves to the body of our Purl Soho Pullover, a bottom-up sweater. The process is quite similar for a top-down sweater and also for a cardigan, so hopefully this video will help with your situation, whatever it is! Follow along…

Hey, this is Laura from Purl Soho, and I’m going to show you how to join the sleeves to the body of a bottom-up sweater that’s knit in the round. Joining the sleeves in the body…it all happens in a single round, or a row if you’re making a cardigan. I’m going to demonstrate it here on this small kid-size Purl Soho Pullover. Now, depending on the pattern you’re working, the steps may vary slightly, but what I’m about to show you, the concept should be very easily applied to whatever your sweater situation. 

So as you can see, I have the body of my sweater finished, worked up to the underarms. I’ve knit one sleeve over here and placed it on hold. And I did that in order to knit the second sleeve, which you can see is still on the needles. One last thing to note before we jump into it is that the underarm stitches for each of these pieces are all on hold. Your pattern may have had you bind off or maybe put them on scrap yarn. 

I’m going to be using the needles that are holding my body and the working yarn coming off of the body to knit around the sleeve stitches. But the first thing I need to do is orient the sleeve and the body so that the underarm stitches are just kind of parallel and just kissing each other, just like this. And you’ll notice that when you do that, when you orient your two pieces of fabric in this way, you’re in the perfect position to begin knitting. You have your body working needle in your right hand and the sleeve-stitch needle right here in your left hand. So for my pattern, actually, the next thing I need to do is place a unique stitch marker, because in my pattern I’m at the end of my round. But if your pattern doesn’t indicate that, don’t worry, just do as it says. But now I’m really ready to begin knitting around these sleeve stitches in order to join these two pieces of fabric together. 

So here I go with the right needle, I’m just going to knit into this first stitch. For this first stitch you might want to give it an extra little tug to secure this join, but here we are. We’ve joined, we’ve officially joined the sleeve to the body, and now I’m going to just continue around the sleeve stitches until I reach the end of the sleeve stitches, and I’ll be at the other side of the underarm. 

So as you can see, I’ve joined the first sleeve to the body. We started right here where I place the stitch marker and knit around, and I’m going to flip it over to show you where I’ve left off. So I reached the end of my sleeve stitches, and as you can see my underarm stitches are still parallel and just kissing each other right here. My working yarn is coming off of this sleeve, this last sleeve stitch now, and I’m ready to carry on and go back to the body stitches working across what for me is the back body. The first thing I need to do in my pattern is place a stitch marker. But again, do as your pattern indicates. So this is, again, a first stitch of moving from one fabric to the other fabric. So I’m going to recommend giving that first stitch just like an extra little tug. And now I’m going to continue across these back body stitches until I reach the next set of underarm stitches. And at that point, I’ll be ready to join my second sleeve. 

Okay, we are in the home stretch. I’ve finished working across the second set of sleeve stitches, and I’m now ready to go back to the body. This time it’s, for my pattern, the front body. And this will working across these stitches will take me back to right where we began. So once again, I need to place a stitch marker. I’m going to drop that on my needle here. And now you can see my underarm stitches are parallel. I’m in the perfect place to join here. So I’m going to take this first stitch, tug it a tiny bit, and now cruise across these front stitches. My pattern has me finish this two stitches before the stitch marker. But do, of course, as your pattern indicates. 

All right guys, we’ve done it. We have joined these two sleeves to the body by working just one single round. These sleeves might seem a tiny bit precarious right now, but as you shape your yoke they’re going to become more and more solidified. And these three, what were just three tubes will become kind of one tube up here at the yoke, and you’re nearly done with your sweater. It’s great. And that’s it. That’s how you join the sleeves to the body of a sweater that’s knit in the round from the bottom up.


Joining the sleeves to the body happens in one single round (or row if you’re making a cardigan). These steps apply to nearly all bottom-up sweaters, except that, for your sweater, the beginning of the round may be in a different place. This means that, instead of starting at the end of the Front stitches, as we do here, you may start at some other place, like the beginning of the Front stitches. Regardless, the steps are the same, just apply these concepts to your specific sweater situation!

Once you have finished the body of your sweater up to the underarms, as well as both sleeves, and all four sets of underarm stitches are on holders or scrap yarn or bound off (depending on your pattern), you’re reading to join the sleeves and body.

You will be working with the body needle and working yarn.

The first step is orient the body and the first sleeve you will be joining. Line up the underarm stitches of the sleeve with the body’s underarm stitches that are right there at the working yarn. Positioning the underarms parallel to each other like this leaves the first stitch of the sleeve in position to knit it. Take the right-hand needle that is holding the body stitches and insert it into the first sleeve stitch. Take the working yarn from the last body stitch and use it to knit the sleeve stitch nice and firmly. Continue around the sleeve stitches, knitting each one off the sleeve needles with the right-hand body needle.

Once you’ve knit the first sleeve’s stitches, you’ll return to the body and firmly knit the stitch right after the on-hold underarm stitches. Continue, knitting across the Body stitches, all the way to the next underarm stitches.

Prepare to join the second sleeve. Slip the on-hold stitches of the remaining sleeve onto some needles, either circular or double pointed, and do exactly what you did for the first sleeve: knit it on! Line up the underarm stitches and insert the right-hand body needle into the first sleeve stitch. Knit it, giving it a little extra tug to bring the body and sleeve together as much as possible. Then knit around the sleeve stitches, using the body needle, until you reach the end of the sleeve stitches, at the other side of the underarm.

Insert the right-hand needle into the first body stitch after the underarms, and to knit it good and tight. Continue to knit across the remaining body stitches.
