Essentially a traditional granny square construction, with puff stitches instead of straight double crochet. The contrast yarn is carried across the rounds, inside the stitches of the main color, eliminating the need for darning in ends. This block has a wonderful texture and would make a great table linen set.

2/4 difficulty.
