I, too, have a fabric related addiction. My son made me aware of it just the other day. I have gotten to the point where I NEED to have items next to my chair to take apart for the fabric. I started doing it out of necessity, but now my hands become very restless if they are idle, and don't have something to be ripping at. I have to hit the thrift store for stuff to dismantle, even if I have no specific use for it.
Since I'm collecting I Spy stuff, I can't find much in clothing and linens that are appropriate for that, so I just buy solids and neutrals and tone on tones in shirts and such; and bedskirts for long sections of fabric with lots of repeats. Anything to feed my habit. LOL
