I need to try out some of those new types of batting...I've been told that wool quilts up really well, especially tight machine quilting, but I've never used anything but W/N and some Poly for charity kids quilts.
I was thinking about the quilt show and the way we did this quilt. Quite frankly, to me, it is no different than doing some thread painting. You do all of that on the top only, then you quilt...so you will also have stitching on the top that doesn't go through to the back...what would be the difference? It will be interesting to see what the judges would really say about it....probably different opinions from however many people you ask.
