My stash if you could call it that is very modest, I use recycled clothing and op shop purchases to make my quilts. I do buy a little if I need a special colour though. I love the challenge of designing my quilts around a colour theme or a particular fabric I have found. There is never enough of course working this way so my quilts are mostly organized scrappy types. I have a couple of large boxes of fabrics, most have been garments which I wash and unpicked and cut into the largest pieces I can. I tend to keep to just a few colour ways, that way everything is colour co-ordinated. Blue is what I am collecting right now, I do put a lot of thought into the planning of a quilt and sometimes I have to wait a good while untill all the fabric pieces are found and I can pull it all together. I like to work this way and everyone seems to like what I do when I give my quilts to them.
I do not know what I would do if I suddenly won Lotto and could go wild in a quilting store, probably come out with fabrics I would never use having bought them on impulse!!
