Thanks everyone for the advice. I chose to use the wool and I think it is an excellent choice. The loft causes the applique to have almost a trapunto effect that really accents the applique. The wool is also so easy to hand quilt. I just completed a pieced quilt with many seams. I used a Hobbs 80/20 batting. It was a labor to quilt, mostly, I think because of the seams. The quilt was Oh, My Stars by American Jane. It turned out really well, but it was on my Grace Z44 frame for three years. I was actually quilting on it with any regularity for six months. It was a difficult quilt--the hand quilting is dense. It does look quite spectacular, however. I will post pictures when my technology expert comes to visit. The quilt I asked for advice about is William Morris and Friends by Michele Hill. The hand applique (back basting) took me a year to complete. The wool batting is working really well and no seams! A pleasure to quilt. I am also enjoying the Hiroshima Tulip between needles I discovered. Thanks again for helping me make a good batting choice.
