We play a fat quarter bingo at retreat, there is a sheet with quilt block names on it available so you all have the same choices, & you make up your own bingo card by writing down which ones you like. You pay 1 fat quarter per card, no limit but it gets a little too confusing after 2 or 3. The caller has all the names from the sheet in the basket & pulls one each time. Depending on how many members participate there are fat quarter prizes for eg. the 1st line of bingo, then maybe a diagonal line, then maybe an x, then the grand finale is for a blackout card that wins the largest bag of fat quarters. It's fun, especially if all members have purchased their fat quarters, not so fun if some have brought some crinkled old piece they had at home....but each to his own.
