Woody1229, I use wool for most of my quilts because of the ease of quilting by hand, it breaths, it lays very nice on the bed.
When I start any quilt project, for some reason, I wash everything. I wash the materials for the top, the batting and the backing. I put the batting in the washer, fill it with water, let is soak for a bit, then drain the water. I don't put it in the dryer, but lay it across my cloths line until it dries. The newer products are far and away better then they used to be.
If you are a hand quilter, you should try a small project with wool before investing in a large quilt.
Good luck, Pam
