I think the fabric will be fantastic. I am working on a OBW. Every motif I open up after cutting is a surprise. They seem to fall in two categories: Stars or Circles, so I am alternating them in the lay out. Because each motif was so fascinating, I'm separating them with a solid triangle of fabric so that each motif stands on it's own. I think a fabric pattern with both straight lines and curves works well to give such a variety of motifs. Eager to see some of your motifs cut out. They will probably be spectacular.
