I don't hang fabric that is not in use - I do hang fabric that is needed for my WIP. I don't use the clip hangers - I use regular hangers made out of plastic that I covered with a little batting and fabric so the items won't slip off. I like to hang the cut pieces like borders and binding - because they have been starched and pressed and I want them to stay wrinkle free. Sometimes I hang the WIP, but only if I think the seams can handle it, and it is usually just overnight or a few days at most. It keeps my cats off the project - that is the main reason I hang it up!
