I have a friend who is regional manager for the Quilts of Valor and she makes "Crumb" quilts for the soldiers. You just keep sewing bits and pieces together until you have at least enough for a 12-1/2" square (she has us sew together about a yard worth of fabric to cut down to several 12-1/2" squares) and then throw the scraps from the trimming back into the scrap bag to be added to more scraps. Then the blocks are sashed together to make a sashed "crazy" quilt. It works especially nice for the QOV because you do not always get large pieces of red, white and/or blue fabric to work with.
