I used to do collage printmaking. (In fact, I used to do batik, too.) I just saw a TV show about a collage technique which uses itsy-bitsy scraps. I can't wait to try the technique out. Fuse the bitsy scraps over design, or attach by sewing with invisible thread, then trim to the outline of the design, then applique the unit. It may not be a new thing yet I'd never seen it. I've always disliked throwing out bitsy scraps.
