Oh! They aren't shirts, just old quilting cottons. I don't think they were washed, or if they were, someone did a nice job ironing/refolding. Someone neater than me. ;)
I think I'll wash them and just take my chances with mixing them. It'd be fairly impossible to keep my washed stuff separate anyway since I always have tons of scraps.
Thanks for the advice, all!
