"The April interlocking crochet square features a geometric quilt-like design. You will need two colors of worsted weight yarn (or weight of your choice, though of course different weights will result in different sized squares) and a size H crochet hook (or size appropriate for your yarn). The pattern comes with charts, written instructions, and a full video tutorial. The sample pictured was made with WeCrochet's Wool of the Andes Worsted yarn and measures 9". Another sample made with Paintbox Simply Aran measured 10"."
