Knitting in the round creates seamless tubes and circles without seams to sew later

Knitting in the round means working in a continuous spiral instead of back and forth in rows. You cast stitches onto a circular needle or a set of double-pointed needles, join them into a loop, and knit around and around. The right side of your work always faces you, and you never turn your needles between rows. This method is the standard way to make socks, hats, sleeves, and the body of sweaters without seams.

The main difference from flat knitting is that you work continuously in one direction. When you reach the end of a round, you straightforward keep going. There is no purling unless the pattern calls for it, and no turning your work. This makes in-the-round knitting faster for many projects and produces a cleaner finished fabric.

Key Takeaways

  • Circular needles and double-pointed needles are the two main tools for knitting in the round, and which you use depends on the circumference of your project.
  • You must join your cast-on stitches into a loop before you start knitting, and the join is the most common place where a visible gap appears.
  • Circular needles work best for larger circumferences (hats, sweater bodies), while double-pointed needles are better for small circumferences (socks, sleeves).
  • The first round is the hardest to tension correctly because the stitches are loose and spread across the needle; tightening the first few stitches prevents a loose edge.

Circular needles versus double-pointed needles

Circular needles have two needle tips connected by a flexible cable. They come in different lengths — typically 16 inches, 24 inches, and 32 inches — and the length you choose depends on the circumference of your project. A hat usually needs a 16-inch needle. A sweater body usually needs a 24-inch or 32-inch needle. The rule is that your needle should be slightly shorter than the circumference of your project so the stitches sit snugly on the needle without bunching.

Double-pointed needles (often called DPNs) are a set of four or five short needles, usually 5 to 8 inches long. You distribute your stitches across three or four needles and use the remaining needle to knit. When you finish one needle, you set it down and pick up the next empty needle. Double-pointed needles work well for small circumferences where a circular needle would be too long — socks, the cuff of a sleeve, or the crown of a hat.

Many knitters use both tools in the same project. You might start a sock on double-pointed needles for the cuff, then switch to a circular needle for the leg, then go back to double-pointed needles for the toe. This is normal and acceptable. Choose whichever tool fits the circumference you are working on.

Casting on and joining into a loop

Cast on the number of stitches your pattern calls for using your chosen needle. The most common cast-on for in-the-round work is the long-tail cast-on, though any cast-on works. Lay your needles flat on a table and arrange the stitches so they sit evenly around the needle without twisting.

Before you knit the first stitch, check that your cast-on edge is not twisted. A twist means one section of your cast-on is facing the wrong direction. To check, look at the bumps along the cast-on edge — they should all face the same way, toward the center of the circle. If one section is flipped, unwind your stitches and reposition them.

Once you are sure there is no twist, hold the needle so the working yarn is attached to the stitch closest to your right needle tip. Knit the first stitch. This first stitch joins your cast-on into a loop. Some knitters place a stitch marker on the right needle tip after knitting the first stitch to mark the start of the round. This marker moves with you as you knit and shows you where each round begins.

Managing tension on the first round

The cast-on stitches are usually loose and spread across the needle. When you knit the first few stitches, they will feel slack and uneven. This is normal. Pull the working yarn snug as you knit the first 5 to 10 stitches, and the tension will even out. Do not pull so hard that you distort the stitches, but do pull harder than you would on a regular row.

A common mistake is to knit the first round too loosely. This creates a visible gap or ladder between the cast-on edge and the first round. To prevent this, many knitters knit the first round with a needle one size smaller than the rest of the project, then switch to the correct needle size for round two. This tightens the cast-on edge without distorting the stitches.

Another method is to knit the first stitch of the first round, then go back and tighten the loop where the yarn connects the last cast-on stitch to the first knit stitch. Gently pull the working yarn to close the gap. This takes practice but becomes automatic once you have done it a few times.

Avoiding the jog where rounds meet

When you knit in the round, the place where one round ends and the next begins is called the jog. Because you are working in a spiral, the stitches do not line up perfectly in vertical columns — there is a small step or jog where the color or pattern shifts. This is visible in striped projects and colorwork.

To minimize the jog, some knitters slip the first stitch of each new round instead of knitting it. This shifts the jog to a less visible spot and makes stripes look more even. Other knitters use the jogless jog technique, which involves knitting the first stitch of the new round, then going back and picking up the stitch from the previous round and knitting it together with the first stitch of the current round. This takes practice but produces nearly invisible transitions.

For most projects, the jog is not noticeable enough to worry about. Colorwork patterns and stripes show it more than solid colors. If your pattern does not mention it, you can ignore it and knit normally.

Switching from circular needles to double-pointed needles

Many patterns ask you to switch needles partway through. For example, a sock pattern might say to knit the leg on a circular needle, then switch to double-pointed needles for the toe. To switch, straightforward knit until you have used up all the stitches on the circular needle. Then pick up a double-pointed needle and continue knitting. The stitches will redistribute themselves across the double-pointed needles as you work.

When you switch from circular to double-pointed needles, divide your stitches as evenly as possible across three needles. If you have 60 stitches, put 20 on each of three needles. Leave the fourth needle empty to knit with. As you knit, the empty needle will fill up, and you will set down the needle you just finished and pick up the empty one.

The transition is usually smooth. The only thing to watch for is tension at the gap where one double-pointed needle ends and the next begins. Pull the working yarn snug when you move from one needle to the next to prevent laddering (loose stitches that look like rungs on a ladder).

Fixing common mistakes in the round

The most common mistake is a twisted cast-on. If you knit a full round before noticing the twist, you will have to unravel and start over. Always check before you knit the first stitch. The second most common mistake is dropping a stitch and not noticing until several rounds later. In the round, a dropped stitch creates a vertical line of loose stitches running down your work. You can pick it up with a crochet hook, but it is easier to catch it right away.

Laddering happens when you move from one needle to the next without pulling the yarn snug. The stitches at the transition point look loose and uneven. To fix it, go back and tighten those stitches by pulling the working yarn. If you are already several stitches past the ladder, you can use a crochet hook to tighten the loose stitches from the back.

If you accidentally knit flat instead of in the round (turning your needles at the end of each round), you will end up with a flat piece instead of a tube. This is hard to fix. The best approach is to unravel back to where you realized the mistake and start the round over. This is why many knitters place a stitch marker at the start of the round — it reminds you not to turn.

Frequently Asked Questions

What size circular needle do I need for my project?

Choose a circular needle that is slightly shorter than the circumference of your project. For a hat with a 20-inch circumference, use a 16-inch needle. For a sweater body with a 40-inch circumference, use a 32-inch needle. If your needle is too long, the stitches will bunch and be hard to work. If it is too short, you will have to stretch the stitches to reach the other needle tip.

Can I use a circular needle for a small project like a baby hat?

If the circumference is very small (under 16 inches), a circular needle will be too long and the stitches will not sit properly. Use double-pointed needles instead. Some knitters use the magic loop technique, which involves using a very long circular needle and folding it in half so only a small section holds stitches. This works but takes practice.

Why does my cast-on edge look loose and sloppy?

The cast-on stitches are always looser than the rest of your work because they are the first stitches on the needle. Tighten them by pulling the working yarn snug as you knit the first 5 to 10 stitches. You can also knit the first round with a needle one size smaller, then switch to the correct size for round two.

What is a stitch marker and do I need one?

A stitch marker is a small ring or clip that slides onto your needle to mark the start of the round. It is not required, but it helps you keep track of where each round begins, especially when you are new to knitting in the round. You can use a piece of yarn or a safety pin if you do not have a stitch marker.

How do I know when I have finished a round?

You have finished a round when you reach the stitch marker at the start of the round. If you do not use a stitch marker, you have finished a round when you have knit all the stitches on your needles. Some knitters count rounds by placing a marker or making a note every 10 rounds to avoid losing track.
