MATERIALS

Purl Soho’s 100-gram Cotton Chirp DK, 100% Peruvian Pima cotton yarn. Each ball of this light worsted/DK-weight yarn is 232 yards/ 100 grams.

  • Main Color (MC): 4 balls; approximately 925 yards required. We used Heirloom White.

  • Contrast Colors (CC’s): 9 balls (1 per color); approximately 180 yards required of each color. We used the colors Chartreuse Yellow, Firecracker Red, Fresh Guava, Golden Honey, Mineral Rose, Pink Ice, Pink Lily, Soft Blue, and Yellow Parakeet.

  • A size F (3.75 mm) crochet hook

GAUGE
One Square = 4½ inches, unlaundered

NOTE: To check your gauge (and save yarn!), we recommend working Square A in a single color without cutting your yarn so you can reuse it. If your square turns out smaller, unravel and try a bigger hook, or if it turns out bigger, try a smaller hook!
