The Mystery RR idea sounds like it could be a lot of fun! Maybe on the week before it is someone's turn they can give fabric requirements for their border, that way if we need to go shopping we'll be able to have the fabric needed before the directions are given? I know some will use their stash, but I don't have a very big one (yet) so might need more fabric.
I will be looking for a "borders" book in the mean time....I do think a new thread would be a good idea too...if someone starts one, please post the link here.
