Written Instructions
Row 1: Single crochet in each chain. Turn.
Row 2: Insert hook through the back loop only of Row 1 and the unused loop from the foundation chain (directly behind it); single crochet across. Turn.
Row 3+: Insert hook through the back loop only of the current row and the unused loop from the row below (now behind the work after turning); single crochet across. Turn.
