I'm making a quilt to be used at the beach as a "beach blanket" and wonder what kind of batting to use? I have to expect that it will get wet and therefore I'd want something that would dry quickly. Also, I don't want it to be too big folded up so it can be carried easily. I've had suggestions from polyester batting to muslin, to nothing in between the layers. Has anyone made this type of quilt? What worked for you?
