Bake cookies? Nah, I don't think so. I've been wanting to try discharging fabric and I picked up some Soft Scrub, regular and gel type, with bleach a while back. I found some old black sheets when I was working on the laundry room. I think they're cotton. I could cut them into FQs and play with the bleach and cookie cutters... Hey, it's too early for spring cleaning anyway!
