If you are interested in getting samples of various battings, Harriet Hargrave sells a sample pack of the 16 different kinds of batting she sells in her store. If I remember correctly, each square is approx. 14", so you can have a sample piece and do a little quilting on it to see how it would work with your quilt. I didn't realize there were so many different types of batting. I especially enjoyed the feel of quilting on wool batting.
