I cut my scraps into the sizes of pre-cuts...2 1/2 in. strips, 5 in. squares, etc.; whatever worked for the pieces of fabric I was cutting up. That way I can make the fun and easy patterns designed for precuts and quickly use up my scraps. Used up a bunch of 2 1/2 in. strips this weekend on a quilt. So nice to only have to cut the background pieces and the strips to the right length.
