About this pattern

A single-crochet square blanket worked in rounds from a magic circle, using one stitch throughout rather than multiple stitch types. Round 1 sets 6 single crochets into the ring; the maker repeats the shaping logic across additional rounds to reach blanket size. A 4mm hook and the recommended Skein yarn (shades like almond, honey, mahogany, truffle, and hazelnut) produce a tight, solid fabric with no gaps, suited to a baby blanket that needs no lining.

This blanket is built from a single square motif worked entirely in single crochet, starting from a magic circle with 6 single crochets in round 1. One stitch carries the whole project, so the only variables are hook size and round count. The pattern specifies 4 rounds for the sample piece before the maker continues to size; expect a dense, hole-free fabric rather than an open lacy one. The count that matters most is that first ring of 6 single crochets — get that wrong and every later round drifts off-square.

Round 1Begin with an adjustable ring (magic circle). Work a single chain to raise the height for the first round. Make 6 single crochets into the adjustable ring. Pull the yarn to close the circle. Connect the circle by crocheting a single crochet into the first stitch made.(6)

Round 2Increase Round Work two single crochets into each stitch from the previous round. By the end of this round, ensure you have a total of 12 stitches.(12)

Round 3Start by crocheting a single crochet into the first stitch and placing a stitch marker. Next stitch, single crochet. Increase at the next stitch by making two single crochets into it. Repeat the pattern around - single crochet in next two stitches, then an increase. Finish this round with a total of 16 stitches.(16)

Round 4Start with a single crochet in the first stitch, marking it. Perform two consecutive increases, each involving two single crochets in a stitch. Continue the pattern: two single crochets and two increases until you have 24 stitches total.(24)

Round 5Begin with a single chain. Skip the first stitch, single crochet in the second. Chain again, and increase in the next stitch by making two single crochets. Continue with: single chain, skip a stitch, then a single crochet into the next one. Include increases at strategic points detailed in the pattern to grow the blanket.

Round 6+Start with a single crochet into the first chain space seen after a single chain. Single chain, skip next stitch, proceed with a single crochet into the next chain space and continue. In corners, work a single crochet, chain, and another single crochet into the same space, creating an increase, necessary for expanding the blanket’s dimensions correctly. Continue with this woven stitch pattern, adding increases in corners and using single crochets linked by chains for the body.

Tester's notes

4mm hook holds the stitch count accurate for round 1's 6 single crochets; a looser hook lets the ring gap open before the first round is even connected.

Place a stitch marker in the first stitch of each round immediately after the connecting single crochet, since the square has no distinct corner stitch to eyeball later.

Keep tension even stitch to stitch rather than row to row; single crochet shows uneven tension more visibly than taller stitches, especially across a flat square.

If changing colors between rounds, join the new color on the connecting single crochet so the color break falls at the same spot each time and stays easy to track.

No stuffing is involved in this flat square motif; the tight, hole-free fabric the pattern produces is the structural layer itself, not a shell to be filled.

The pattern recommends using a 4mm crochet hook and Skein yarns in shades like almond, honey, mahogany, truffle, and hazelnut.

Gauge check

After round 1, lay the ring flat and confirm all 6 single crochets sit evenly around it with no gaps and no stitch doubled up on another.

If the ring puckers or won't lie flat at round 1, pull back to the magic circle and re-close it tighter before continuing, since every later round compounds that first count.

If something looks wrong

The piece cups instead of lying flat.: Too many single crochets have been added in an early round relative to round 1's count of 6. Unravel back to the last flat round and re-check the stitch count before continuing.
The ring won't close tightly after the: The magic circle's tail wasn't pulled firmly before the first connecting single crochet. Snug the tail again now, even mid-round, rather than carrying a loose center through every later round.
The square has a visible seam line or: The connecting single crochet into the first stitch is landing inconsistently. Mark that first stitch every round so the join always closes in the same spot.
The fabric looks looser or has small: Hook size has drifted away from the 4mm called for, or tension loosened partway through. Recheck hook size and work a few stitches more snugly to match the earlier rounds.

Yarn substitutions

Cotton yarn	Produces a firmer, less stretchy square with crisper stitch definition; keep the 4mm hook, but expect the finished piece to run slightly smaller and heavier than the same round count in the recommended Skein yarn.
Acrylic-wool blend	Keeps drape close to the original fabric while adding a bit more loft; the 4mm hook still applies, and color changes between rounds stay simple since blends take dye evenly.
Acrylic, DK weight	Makes a thinner, more pliable square at the same round count than the recommended yarn; size up to a 3.5mm hook to keep the fabric as tight and hole-free as the original.

FAQs

Questions

Can the square be made larger than the 4 rounds shown?

Yes. The source notes say to continue the same round pattern to grow the piece to the desired dimensions, since the logic set in round 1's 6 single crochets repeats outward.

Does this pattern use more than one stitch type?

No. The title and the instructions confirm the entire square is built from single crochet alone, starting from the 6-stitch magic circle in round 1.

What hook and yarn does the pattern call for?

The pattern specifies a 4mm hook and recommends Skein yarn in shades such as almond, honey, mahogany, truffle, and hazelnut, which produces the tightly woven, hole-free fabric noted as suited to a baby blanket.
