My LQS has a monthly block lotto. She supplies a focus fabric and a pattern, we supply coordinating fabrics and $.50 per block that we want to do. She has a basket of coordinating fat quarters right by the patterns so people can pick up what they need if they don't want to shop their stash or have problems figuring out which fabrics go with which. She puts out the block on the first of every month and your block is due back before the end of the month. When you bring in your completed block, the block is displayed (makers name on the back) and your name is put in a jar from which the name of the winner of all the blocks is drawn at the end of the month. Of course, the winner will need the focus fabric for sashing, borders, binding, batting and backing...all to be purchased from the LQS!
