How about this:

It's about a "new and better machine" which we quilters are always looking for! It talks about throwing something small over a wall, and the "new and better machine" throws back an improved model! For instance, throw a couple of fat quarters and get a sewn quilt block. Then throw a quilt block and get a baby quilt. Do this a few times, then have someone new throw something new over and get no return. Repeat this wtih no return again. In disgust spit at the wall and the wall throws a bucket of water (substitute water-colored confetti) on the person. Messy but could be cute and relatively easy to pull off.
