What a great question and I appreciate everyone's ideas.
I think someone mentioned it, but I use some scapbooking plastic boxes from Micheals to keep my current project in. As I finish each block it goes in the box with patterns, cut fabric etc.
I don't have a design wall yet, but a friend of mine has a big wall of shelves she keeps fabric and books in and then has a piece of flannel on a roll at the top that she unrolls when she uses it. An yes she does roll projects up in it too.
I think I will get my graph paper out and try to come up with a plan for my new room, if I could ever get the finished.
