Sharongn, thanks! I actually was still bothered by the Fabric A possibly being overshadowed by some of the other fabric patterns (I think the elements are just too small in that pattern) so I broke my own self-imposed rule to only shop my stash and bought a new Fabric A in the same color palette, which I think works much better. LOL, I thought I'd be done mixing and matching after the cutting was done but apparently it's just too much fun to resist!
That's definitely one of the best parts of quilting- falling in love with a fabric and knowing it'll eventually have a good home in a quilt at some point, but the "when" and "which quilt" are a mystery!
