I assume the theme is orange not Halloween. if we do red, you do not mean christmas. If we do green, I assume you do not mean landscape grasslands etc. I don't think I have any Halloween but I do have pumpkins and fall foliage, and I know I have no christmas fabrics. That said, I'll be searching my stash for 80% orange. If I don't have enough, I'll have an excuse to go to the Local Fabric Store and buy a little more than I need for the swap so i can hoard a little orange for myself. I'll look in modern, blenders, 30's, traditional, all across the spectrum. Count me in, even though this is a hard color. But we should all carry some in our stash for a balance.......Jane
