Another whole cloth quilter to gain inspiration from is Karen McTavish.

I would not recommend using Dupioni for a bed quilt. This fabric is usually reserved for wall hangings and show quilts. The silk blend radiance is slightly more suitable but is very pricey and is recommended to only hand wash or dry clean. So I would not consider it for a quilt that is going to be well used and loved.
