I am not one to cut scraps until I know what quilt pattern I will use them in, then cut for that---believing leaving scraps in the largest size gives me more options for using them. However, if your pile are already cut into smaller pieces/squares, I think I would find a scrappy quilt pattern first, then start cutting/trimming them to the size needed in that pattern. Obviously I am one to select my pattern/design first, then mess with the fabrics to fit. Good luck and have fun with your new stash!
