How to Join Knitting in the Round

Learn how to join your knitting in the rounds to knit hats. This technique is a simple and easy way to join knitting with cable needles.

To knit beanies or hats we need to knit in the round. This means we’ll knit around and around in a circle.

If you use straight needles to primarily knit flat, then eventually you’ll need to learn how to knit in the round.

Several stitches cast on and knit in the round using cable needles.

You can knit in the round with either DPNs (double pointed needles) or with cable needles (knitting needles attached to cables with the needles at either end).

Like most knitting techniques there are various ways to knit in the round. Here I’m going to show you how I join to knit in the round with cable needles.

For this tutorial I’m knitting with Red Heart With Love in the color Cameo. It’s such a pretty purply pink.

This is a nice soft #4 medium worsted weight yarn from Red Heart. You can use any yarn for this technique if you’re just practicing.

Pia from StitchesNScraps has a really nice tutorial for an alternating cable cast on, or seed stitch cast on that works well for hat ribbing.

Learn how to join to knit in the round using cable needles.


  • any weight yarn; I'm using a #4 medium worsted weight yarn


  • 16" + circular knitting needles in size that matches your yarn; I'm using my 4.5mm needles on 16" cables.


  1. Cast on with cable needles. For the Trento Hat, which is knit with this size yarn and needle, I cast on 84 sts for Teen/Sm Adult size.Pink stitches cast on circular knitting needles. Be sure it’s not twisted.
  2. Turn your work so the working yarn (attached to the yarn ball) is coming from the right needle.
  3. Bring needles together.
  4. Knit first stitch on the left needle.Knit first stitch on left needle. When you slide the stitch to the right needle it will form a connection between the first and last stitches. You have joined in the round.
  5. Continue to knit around.
  6. When you get back to the first stitch you knit, place a stitch marker-or use the tail to note your beginning stitch.
  7. To knit in the round you'll just keep knitting when you come to that first stitch, around and around.
  8. There will be a slight jog from cast on to row 1, but you can easily straighten that out when you weave in your tail.


There are several ways to join knitting in the round on circular (or cable) needles. Personally, I find this the simplest way.

To knit in the round you'll need at least a 16" cable for hats. If you will be decreasing (or knitting something smaller like a cuff) you'll need to use a longer cable (32"+) and magic loop method or DPNs.
