The disappearing pinwheel is a Missouri Star tutorial. I just went to youtube and searched for disappearing pinwheel quilt pattern. There are 2 layouts for the block. The one I am making and also one that looks like a churn dash. It uses a layer cake. I am not a precut kind of girl. I like to make my own combinations. It goes really fast. After you make the pinwheel you cut it in thirds and sew it back together. I have 32 blocks finished now. I hope to finish the blocks tonight.
