There is a product called rinse away, and also one close, by Ricky Timms, but can't remember name. It is a stabilizer type product. But you can put it under your applique piece so that when you applique it onto the main fabric and wash the quilt, the product washes out, but leaves a little bit of fibers inside and makes the puff. I haven't tried it yet, but have seen some quilts done with it. Looks nice, with just a little puff, like your pictured quilt.
