I was thinking maybe precut some strips....maybe 2 to 5 inches wide. Then let them sew them in any order they want. Maybe the size could be a doll size or table placemat. 3 or 4 pieces would be enough. Trim them off even and add a back and backing. Let them quilt it by sewing along the middle or any way they want to. Might could be done in 3 hrs.
