How to Crochet in the Round: From Center Ring to Flat Circle

Hats, amigurumi, doilies, mandalas, and any circular blanket are built the same way: a small ring at the center, stitches worked outward in concentric rounds, with planned increases that keep the fabric flat as it grows. Once you know the increase math, every flat-circle project uses the same logic. The only thing that changes between an amigurumi octopus head and a circular rug is yarn weight and round count.

This guide covers the two ways to start the center, the increase rule that keeps your circle from cupping or rippling, and a four-round practice project.

The increase rule

When you work in rows, each row has the same number of stitches as the one below it, and the fabric grows vertically as a rectangle.

When you work in the round, each round wraps around the one before it. The outer round has a longer circumference than the inner one. If you don't add stitches as you go, the fabric can't lie flat: too few stitches and it cups (pulls inward like a bowl), too many and it ripples (waves at the edges).

The rule for double crochet on a flat circle: add 12 stitches per round, distributed evenly. For single crochet: add 6 stitches per round (same logic, smaller increments). The numbers come from circle geometry. Each round needs about 2π more stitches of circumference than the one inside it, and 6 or 12 is the closest practical match for the stitch height.

In practice this means:

Round	Stitches (dc)	Increase pattern
1	12	12 dc in ring
2	24	2 dc in every stitch
3	36	(2 dc in 1st, 1 dc in next) repeated
4	48	(2 dc in 1st, 1 dc in next 2) repeated
5	60	(2 dc in 1st, 1 dc in next 3) repeated

Single crochet starts at 6 and follows the same pattern: 6, 12, 18, 24, 30, 36.

Patterns spell this out, so you don't have to memorize it. But understanding why the increases sit where they do means you can troubleshoot a cupped or rippled circle without re-reading the pattern five times.

Two ways to start a round

Both methods produce a working ring at the center. Pick based on what the center will look like in the finished project.

Chain ring

The classic. Easiest to learn.

1. Chain 4 (or whatever the pattern says: 4 is typical for double crochet, 2 for single).
2. Slip stitch into the first chain to form a loop.
3. Chain 3 (or 2 for sc projects). This counts as your first stitch of round 1.
4. Work the rest of round 1's stitches into the center of the loop.
5. Slip stitch to the top of the starting chain to close.

Leaves a small visible hole in the middle. Fine for blankets, doilies, anything where a center hole reads as part of the design.

Magic ring (adjustable ring)

Closes flat in the middle, no visible hole. The right choice for amigurumi and any closed fitted circle.

1. Drape the yarn over your fingers so the tail crosses over the working yarn, forming a loop.
2. Insert the hook into the loop, hook the working yarn, pull a loop through.
3. Chain 1 to lock it in place. This chain doesn't count as a stitch.
4. Work round 1's stitches into the loop, catching both strands of the loop, not just one.
5. Slip stitch to close round 1.
6. Pull the tail. The loop cinches closed at the center.

Magic ring takes a few tries to make consistent. The first three you make will be lumpy or twisted. The tenth will be automatic. Worth the practice once you start making any closed circle where the center would show.

Joined vs continuous rounds

Two ways to handle the end of each round.

Joined rounds. Slip stitch to the first stitch of the round, chain up for the next round, work around, slip stitch to close, repeat. This creates a visible "seam" running up one side of the work where the slip-stitch joins stack.

Continuous rounds (spiral). Don't slip-stitch at all. Place a stitch marker in the first stitch of each round, work around, when you reach the marker move it up to the first stitch of the next round. No seam, no jog. The fabric spirals.

Spirals are the default for single-crochet projects, especially amigurumi. Joined rounds are the default for double-crochet projects, including most blankets and hats with rib bands. Patterns specify which one to use.

If you don't have a stitch marker for the spiral method, a piece of scrap yarn in a contrasting color works. So does a paperclip or a small safety pin.

A four-round practice project

A single-color coaster, big enough to demonstrate the increase math, small enough to finish in 20 minutes.

Materials: worsted-weight yarn, 5mm hook, scissors, yarn needle.

Round 1: Chain 4, slip stitch to form a ring. Chain 3 (counts as first dc). Work 11 dc into the ring. Slip stitch to the top of the starting chain-3. (12 dc)

Round 2: Chain 3 (counts as first dc), 1 dc in the same stitch (this is your first increase). Work 2 dc in each remaining stitch around. Slip stitch to close. (24 dc)

Round 3: Chain 3 (counts as first dc), 1 dc in the same stitch, 1 dc in the next stitch. 2 dc in the next stitch, 1 dc in the stitch after that. Repeat from * around. Slip stitch to close. (36 dc)

Round 4: Chain 3 (counts as first dc), 1 dc in the same stitch, 1 dc in the next 2 stitches. 2 dc in the next stitch, 1 dc in the next 2. Repeat from * around. Slip stitch to close. (48 dc)

Cut yarn, pull through the last loop, weave in the two tails. You should have a flat circle about four inches across.

If it cups, you're working too tight or you missed an increase. Try again, adding one more increase per round.

If it ripples, you have too many stitches, probably because you added an extra increase by accident. Recount and try again.

A pattern that uses these techniques

After the practice coaster, the natural next project is one with more rounds and a slightly more decorative stitch pattern. Same skills, more of them.

Sunrise Coaster

Find this pattern on HoneyBee

Toni Lipsey. Worsted weight, 5mm hook, beginner. Built on the same increase logic as the practice coaster above, with a sun-ray stitch pattern that demonstrates how textured stitches sit on top of the basic flat-circle structure. Reversible. If you can make the four-round coaster, you can make this one in under an hour.

When you're ready for amigurumi

Amigurumi is crochet in the round in single crochet, usually on a smaller hook than the yarn would suggest (a 3.5mm hook with worsted yarn, instead of the usual 5mm), so the fabric is dense enough that the stuffing doesn't show through. Same magic-ring start, same increase math (the single-crochet version: add 6 stitches per round). The differences are decreases (for shaping necks, heads, limbs) and stuffing as you go.

Read an amigurumi pattern start to finish before starting. Most are written in continuous rounds with single crochet and use sc2tog or invisible-decrease techniques. Both of those are easy to add on top of the foundation you'll have from making a few flat circles.

FAQ

Why does my circle have a visible jog where the rounds meet?

You're working joined rounds. The slip-stitch join always creates a small step. Switch to continuous rounds (no slip-stitch at the end of the round, stitch marker to track where the round starts) and the jog disappears.

Can I crochet a flat circle in any stitch?

Yes, but the increase count changes. Double crochet flat circles need 12 stitches in round 1 and add 12 per round. Half-double crochet sits between sc and dc, usually 8 per round. Single crochet starts at 6 and adds 6. Test on a small swatch before committing to a project; if it cups or ripples in the first three rounds, the math is wrong for the stitch.

Does chain ring or magic ring make a difference for blankets?

Not really. A blanket's center is small relative to the whole thing, and once it's on a couch you won't be looking at the middle hole. Use whichever you find faster.
