That's a good idea GAyle to store fabric in the garage but that wouldn't work here in Ottawa, Canada. I'd freeze my butt trying to find the one fabric I am searching. :-)
Do you have time to sew some of it? I understand about not being able to stop. I tell my kids that if I die before I use up all my fabric, they can sell it on Ebay. That's their inheritance. At least I didn't drink, smoke, gamble or take drugs with my money. They can recup it. But I plan to start using it all as soon as I retire next year. Right now, I do get some sewing done but not enough for my liking.
