Gossamer Square is available for free on the ItWasYarn blog!

This square is the November Main Square for BAMCAL 2026 (Block-A-Month Crochet Along).

Gossamer Square is a colorful, lightweight square with a delicate, slightly lacy texture. Worked in rounds from the center outward, it’s a lovely addition to blankets, afghans, and other crochet projects.

Choose your square size

The sample shown in the photos was made with sport-weight yarn and a 3.5 mm (US E-4) crochet hook. It measures approximately 8 inches (20 cm).

Want a standard 12-inch (30 cm) square for your afghan? Use Aran-weight yarn and a 5 mm (US H-8) crochet hook instead. The larger version is designed to pair well with other 12-inch squares.

The finished square has 39 stitches per side, with ch-2 spaces at the corners.

Gauge

For the sport-weight version:
20 sc × 18 rows = 4 × 4 inches (10 × 10 cm).

Gauge is not critical for this project, but it will affect the finished size.

Finished size
