I don't cut my scraps till I know what pattern I want to use. At one time I did cut them before having an idea and the pattern I had finally had my heart set on was not the size of the pieces I cut. So now I just sort by lights , mediums and darks.. Some get sorted by type batik, metalic and other. I do have a bin of fall color fabrics , as that colorway is the one I favor most.
My advise .. pick a pattern then sort , then cut.
