I almost always use Warm & Natural, because I love its softness and drape and the slightly crinkled look when you wash it after the quilt is complete. It is also the most readily available cotton batting in my area of California. At Road to California last weekend I got a sample and a queen size of washable wool batting at the Hobbs booth, and I can't wait to try it. Hobbs always has "sample packs" at their booth, and you get about 7 different batting samples for $5. I will spend some time working with the samples to see how I like the feel. I only machine quilt, so not sure I will actually "feel" a great difference during the making of the quilt.
