This easy crochet blanket boasts a classic solid granny square motif that’s worked in double crochet. Joining each round in the corner of the granny square results in a smooth, seamless look thanks to the invisible mattress stitch that gives it a neat finish. Caron Cotton Cakes, a self-striping worsted weight yarn, makes it easy to create colorful coordinating squares without having to change yarns. We’ve used modern shades for today’s contemporary looks, but the pattern can be customized to feature any colors that make this throw perfect for you.
