I try hard not to buy too much fabric. I have one closet with shelves for "stash" and some overflow. I also have some containers that have planned quilts (all the fabrics but not patterns). But I am steering clear of fabric stores unless I just need something to go into something I'm working on. I do not want to be buried in fabric and some of it I'll get tired of before I even use it.
But, you're right, there are some you just can't seem to cut in to.
