My guild plays Christmas bingo, each making a block with 5 rows of colors in different patterns, (paisley, stripe, Christmas prints, etc) then we gather up the blocks and make a quilt for charity from them. We play the right/left gift exchange, too, reading "The Night Before Christmas" and changing directions each time "and" or "the" is read. We each bring an item for the bingo prizes, letting the winners have their choice of the items.
