You could try buying it on line. If you do a google search and use "hobbs heirloom batting" in quotes you will get a ton of hits. I just tried it and found a few sources. Here is a link:

They charge $13.98 for the queen size. I have a big Joanns in my area (I checked the on line store and they don't seem to offer it on line) and whenever the quilt bat goes on sale I stock up big time. So I haven't had to buy any quilt batting in a long time, other then a black one I just bought for a black quilt I am making.
