Reading through other's responses has brought me to a conclusion. I don't have a stash, as I said earlier, however, I have quite a few WIPs. For me, those have taken the place of a stash. Since I don't do my own designs when the urge to create strikes I go and sew on one of my projects.
I have thought many, many times how nice it would be to just think about making a quilt, shop my stash and then complete it (or at least the top). I admire those that can do that. Especially when the need for an 'emergency' quilt comes up.
I have however, a sort of toy stash. I purchased my sewing machine, my spinning wheel and other 'stuff' that goes with that, as well as knitting needles and supplies when we had two incomes. I'm glad I did that because now with just the one income I have the hardware and just have to get materials. It is much easier to afford fabric and yarn than a machine or other tools.
