I don't think I set out to build a stash - it started by leftover fabric from sewing projects. Then when I was planning a quilt I would buy 1/2 yd. or so extra just in case I miscalculated the yardage. Then there is the fabric that jumps off the shelves in front of me and I just have to buy it, as I know it won't be there when I go back, even though I have no particular quilt in mind. Of course there is simply buying fabric on sale at a great price for future projects. Although that can get me into trouble occasionally, like having to downsize from house to apt., where I have lots of "stash", since we've moved I have made several quilts - crib to king size - and picking fabric entirely from my stash. I do miss shopping for fabric though, so every so often I indulge when I have the time, opportunity and money.
