Actually I used a wool batting I had on hand and I'd like a little more poof. I tried 2 layers of the wool but the foot got snagged. That being said, the design is about 5x5 so I might not be able to get much more. I'm going to experiment with a cotton low loft layer on top of the higher loft wool and a bigger design to see what I get.
I'm turning my sister's satin wedding dress into a wall hanging quilt so I need to get this perfect before I move on to the real fabric and yes, I'll be buying extra satin fabric to experiment with as well.
