My biggest problem with pre-cuts is that so many pieces are left over after many projects-more scraps. Granted they are cut into specific sizes-but they are scraps. Either I have too many pieces and create scraps or I don't have enough pieces because I have already used part of the bundle. I have a couple of patterns using charms that I use for kid donation quilts; but, I am about to give up on pre-cuts in favor of just buying yardage.
