Well I only started quilting what...two weeks ago? So my stash is still small (only in comparison to some of the pics I've seen on here!), but it's working well for me. I can see how it could accumulate very fast though.
I went to JoAnn's with my MIL and drooled over all the gorgeous fabrics (okay...not literally drooled, don't worry!). But I haven't bought any fabric yet (I've been given a lot from MIL and a few very nice ladies) as I feel bad spending DH's money. I don't have a job and I know he wants me to get what I want, but I feel bad spending it on me.
Still, I think we're going to work it out so I get an 'allowance' and then I won't feel as bad. Something low like $5 every other week would be good...keep the stash down but still be able to get what I need. :)
