I just made a mystery quilt where it called for larger cuts than I had. I I needed 3 yards of one color. I just used several different reds that I had that were about the same value. I just used then randomly. I did the same thing with the other colors in the quilt. It looks really good and it added some interest to the design. I also quit buying quilt backs trying to use up my stash. I piece them out of what I have.
