I do the same thing, only I recycle empty fabric bolts from Joann's - I can get 4 of them out of one complete bolt, then I fold my fabric around and secure with a straight pin. I don't have quite the stash that you do, but I'm quite sure I have more than I think I do....and the last quilt I made emptied many of my little bolts - is this a valid excuse to buy more fabric? Oh, wait, I already did!
