I sometimes buy the fleece when it is a good sale and use it for batting in some on my quilts. Last time they had a good sale I bought a whole bolt of white fleece. It is cheaper and warmer than quilt batting. I must admit I have never used wool. I have some for a quilt I am making now for my DD who is always cold. The fleece is only 60 inches wide so I do have to piece it sometimes.
