One of the few classes I've taken was a hand quilting class.I said at the beginning of the class that I'd been hand quilting for over 15 yrs But could always learn more! Boy did I!
One of the things she did was to make a practice sandwich with 4 different kinds ofbatting. She had a circle drawn for us to practice on. The best to quilt on was the poly.,but the wool was almost as good. I like natural fibers so wool is what I've been using & the more I use it the more I like it. It's cool in summer & warm in winter! My stitches are getting smaller & smaller!
