OMG>>>gifted....REALLY GIFTED!!! Those are like nothing I've ever seen! Since I can't sew...those just astound me! It would have to be PP for me to have a prayer of doing one even close to those, then in no way could I do all the embellishment that they have.
Now...how to set them? I'd think something very plain and simple to allow the blocks to speak for themselves. I think bandana type fabs...to keep your colors and themes going. I like the curving FG thought mentioned earlier too....
