Pearl40, Looks like a disappearing 9patch? It looks like you collected quite a variety of B&W prints! Nice job.
OK, another way to make that idea that I've seen is to use netting-- a large hole netting over the top of the threads and fabric trimmings. If you use a fine small hole mesh then you can't see the pieces through it well. It can make an interesting wall hanging. I've seen them decorated with large embroidery stitching, sequins, beads, etc.
