Pattern Description:

Skill Level: Intermediate – familiarity with puff stitches, color changes, and working in the round is helpful.

The Rainbow Puff Square is a cheerful and colorful crochet motif adapted from the original Rainbow Puff Hexagon design by Crafty CC.

This square version keeps the beloved puff stitch texture while transforming it into a more versatile shape, ideal for joining into blankets, pillows, or other patchwork projects.

Hook: A 3mm hook is ideal to prevent the second yarn from peeking through, though it can make the square stiff. To create a softer square or to reduce curling, consider using a 3.5mm or 4mm hook.
Notions: Tapestry needle and scissors.

Abbreviations:

Ch: Chain
SC: Single Crochet
DC: Double Crochet

Special Stitch – Puff Stitch (4DC Puff): YO, insert hook into the ch-2 space, pull up a loop. Repeat this 4 times (you’ll have 9 loops on the hook). YO, pull through the first 8 loops. YO again and pull through the final 2 loops.

Pattern Notes:

Colour A is used as the base throughout all 8 rounds. Other colors are worked only in puff stitches.
The square begins with a magic circle.
Each puff stitch round incorporates one rainbow color, which is cut after that round.
Carrying yarn can lead to visible threads. For cleaner results, cut and rejoin colors, even though this creates extra ends.
If the square starts to curl, increase your hook size.
Maintain even tension to avoid yarn from showing through the stitches.
