How to Knit in the Round: DPNs, Magic Loop, and 9-Inch Circulars

Knitting in the round means working in a continuous spiral rather than back and forth, so you never purl a right-side row — your stockinette is always knit stitches going forward. It's the method behind socks, hats, mittens, seamless sweaters, and any tubular piece. There are three tools for the job, each with its own strengths.

The Three Methods

Double-Pointed Needles (DPNs)

DPNs are sets of 4 or 5 short needles — typically 5–7 inches long — where stitches are distributed across the needles in a triangle or square, and you use the extra needle to knit from one to another. They're the traditional method, and many knitters find the feel intuitive once they stop fighting the floppy needles.

Best for: Small circumferences (sock toes, i-cord, thumb gussets, top of hat crowns), situations where you need to decrease rapidly to a small number of stitches, or when you prefer the feel of shorter needles. Also handy as cable needles in a pinch.

The setup: Cast on all stitches onto one needle, then distribute them evenly across 3 or 4 needles. Arrange in a triangle or square. The yarn tail marks the beginning of your round. Hold the needle with the working yarn in your right hand, and use the free needle to begin knitting.

Magic Loop

Magic loop uses a single long circular needle (at least 32 inches, 40 is better) with a flexible cable, pulling a loop of extra cable out the side between stitches to accommodate small circumferences. It sounds strange, but it becomes second nature within a few rows.

Best for: Knitters who dislike juggling DPNs, projects where you want to try both socks or mittens at the same time (two-at-a-time magic loop), and any small circumference project where you already own a long circular.

The setup: Cast on all stitches, fold the work in half, pull the cable out between the halfway point to form a loop on each side. You'll have half the stitches on each needle tip. Knit across the front needle, pull cable through to expose the back half, rotate, and repeat.

9-Inch (Short) Circulars

These are circular needles with a very short cable (7–9 inches total), designed specifically for small circumferences — socks, hats past the decreases, sleeves. They feel the most like "normal" knitting because there's no cable loop to manage and no needle juggling.

Best for: Knitters who find magic loop awkward and DPNs frustrating. The learning curve is minimal if you already knit on circulars. Not useful for large circumferences, and you may need to switch to magic loop or DPNs for the very tip of hat crowns.

The Deadly Sin: Twisting When You Join

When you first join to work in the round, every stitch must hang down from the needle in the same direction — none can be twisted around the cable or needle. A twisted cast on produces a Mobius strip: you'll knit a full round and realize the fabric spirals instead of sitting flat. This is not fixable without frogging.

Before joining, lay the cast-on stitches flat on a table and make sure they all point consistently downward, with no twists. Double-check after placing markers. The join itself: simply knit the first cast-on stitch with your working yarn — there's no special connection needed beyond that first stitch.

A trick many teachers use: cast on one extra stitch, slip it to the left needle from the right, then knit those two together as your first stitch. This tightens the join and eliminates the gap that sometimes appears at the beginning of round one.

Managing the Jog at Round Joins

In stripes and colorwork, the "jog" is a one-row step that appears where each new round begins, because rounds are actually a continuous spiral rather than perfectly stacked rings. On a striped hat, this shows as a staircase at the color change.

The jog fix: after knitting the first round in a new color, insert the right needle into the left leg of the stitch below the first stitch of the round and lift it onto the left needle, then knit it together with the first stitch of round two. This pulls the color change up and hides the step. It works beautifully for stripes of two or more rounds. For single-round stripes, jogless methods are more involved — look up the "Jeny's magic stripe" technique.

Reading Charts in the Round

This is where many knitters trip up. Flat knitting charts are read right to left on RS rows and left to right on WS rows (because you're turning the work). In the round, you're always looking at the RS — so every chart row reads right to left, every row, without exception. If a chart says "purl on WS," that row becomes a knit row when worked in the round. Many patterns annotate this, but always double-check with the pattern notes.

Mark your beginning of round with a split-ring marker in a color you'll recognize, and count your rounds — charts for in-the-round work and flat work look identical, so the direction you read is the only difference.

Quick Decision Guide

• Socks from cuff down: DPNs, magic loop, or short circulars — all work. Choose by preference.
• Hat body: 16-inch circular is ideal; switch to magic loop or DPNs for crown decreases.
• Seamless sweater body: 32–40 inch circular. No switching needed until armhole division.
• I-cord: DPNs only (slide stitches to other end without turning).

Whichever method you choose, the first round is always the hardest. By round five, you'll have found your rhythm. Ready to try a project in the round and want help choosing the right method? Ask KnittingFix — describe your project and we'll point you to the right technique.
