Have to add that I don't particularly like the Kona cotton I have bought at my LQS because I find it too heavy and stiff. I usually buy Moda solids. However, I just took a class that calls for a foundation, and the instructor recommended using Kona white rather than tear away paper (too annoying) or muslin (too stretchy and light). Next time I'm in Joann's I will look and see what the end of the bolt says.
