I've gone through a number of Moda layer cakes, and in general I see a handful of duplicates in each pack. Once in a while on a smaller line there will be a triplet or two. When I am cutting my own layer cakes (for specific patterns) I try to make sure I have a good balance of light v. dark pieces (50/50 if I can get it), and an eye-pleasing mix of strong designs and colors v. solids, blenders, and more "restive" pieces.
