I would like to do this but I have a problem. We live way out in the middle of nowhere. If I have already done my monthly shopping trip, I have to wait till next month to get fabric or buy it online and wait who knows how long for it to get here. I do have a lot of fabric here at home, but if I don't have anything suitable for the assigned block, then what? Can we pick someone who wants a block in colors we already have on hand?
