You are only paper piecing the half square triangles of the various sizes from 2 pieces of a layer cake (one layer cake and a solid layer cake). Various arrangements of the pieces are shown on the cover of the Cake mix. There are at least 4 "recipes" (booklets) and there are 42 (or 44 --can't remember) paper sheets in the tablet (enough to have a couple spares). Excellent for beginners and intermediates alike.
