From the Knit Picks Website:

Three circular knit washcloths in bright, happy colors. Perfect for any bridal shower or housewarming gift.

Needles: Size 6 (4.0mm): 16” circular

Pattern Errata:
In the Zig-Zag washcloth, R1 should read “yo, k2” to end and that will give you 15 sts. Also, on R14, there should be a yarn over after the second decrease. So it should read “K5, ssk, yo, k2tog, yo, k to marker.”

Double points or two sets of circulars are required for the small diameter knitting on all patterns.
