I have a HUGE stash, too. I am trying to limit myself as to what I buy. This month, I bought 6 yards. I bought the end of the bolt which she charged me for 2 yards but it was actually 2 1/2 yards. Good deal but it is just more for my stash.
I am also keeping track, (silly me) of what I use from my stash for I don't want it to grow any more. So far this month I have used 2 1/2 yards so I need to do some pretty serious sewing before the end of the month to keep the stash in a negative trend. Well, I have a week left for July. So I have plenty of time to work on my stash.
