Mosaic Square 12

This geometric mosaic square is worked from the center outward in 14 rounds using the overlay mosaic crochet technique. Two colors alternate every round without cutting the yarn. The design combines two ideas from the Basic Mosaic Collection: the concentric ring structure of Pattern 1 and the alternating double crochet texture of Pattern 2 — creating a layered geometric result that looks more complex than it is to make. Double crochet appears in both colors at different points in the pattern: in Color A at rounds 3 and 11, and in Color B at rounds 6 and 14. All other rounds are plain single crochet worked in the back loop. The written pattern includes a full row-by-row description with stitch notation for all 14 rounds, plus detailed notes on corners, joins, color changes, and how to pick up the previous color on the first stitch of every round.
