My stash has yardage (that I love) of a black on black, white on cool white, and steel grey with a fine charcoal crackle, going to use these with an assortment of (+/- 8 each) reds and yellows.....that is my plan...unless.....like in some of the other mysteries there is strip piecing on papers to 'make fabric' then i'll need to dig deeper into scraps.
