Does dk yarn come in different thickness? I like making the “magic potholder” (for those not familiar with this pattern: the potholder that you crochet around and around and it holds in on itself and is then sewn together.) Anyway, I’ve mostly used WW cotton yarn but thought they were too thick. So I bought some dk yarn and it is so thin. Almost feels like a sock weight. Does anyone know if there is a brand of dk yarn that is thicker?
