Unless you plan to get into scrappy stuff, you don't really need a stash. I have lots of fabric in bins because I've been doing some scrappy stuff the last few years but before that I really didn't see the need for it. I alway bought what I needed and had very little left over so I didn't accumulate much. My space is limited and so is my budget so I try to only buy for specific projects and even doing that it starts to build.
