Here's another suggestion: Buy (or even better, make!) one of those large "nets" that are used in school gyms to hold basketballs, volley balls, etc.) and hang it from the ceiling in one corner of your sewing room. If you aren't familiar with these, they look basically like rope "hammocks" when they are hung from the ceiling. They would probably work well for holding fleece (which is bulky but not too heavy). ('Wish I had a picture to show you, as this might not make much sense unless you've actually seen one of these before.)
