"Sew Be It" has several patterns that would work using upholstery or decorator fabrics. Their pattern "The Main Feature" has example done in Asian fabrics that I saw made up at a LQS using dec and silk fabrics in large sections. I've used large print dec fabrics in collage quilts as Rosemary Eichorn (
www.sewjourn.com) taught. Her website would be good to check out if you want to go in that direction. Have fun searching as I'm sure you'll come up with an idea that speaks to you. The fabrics will talk.
