Yes, since I was a child getting scraps from my mother. I also turned the collars on DH's shirts when we were newly wed, made baby sleepers from old cotton sweatshirts, denim toddler coveralls from worn thin jeans, patchwork cushions.
Over the years my stash has grown with bargain fabrics--sewing factory cuts, orphan blocks & patches, thrift & yard sale goods, rummage sales, immediate family worn clothing, feed sacks, wool blankets and clothing, and remnants. Now that I'm retired the stash is steadily becoming an organized fabric collection.
The funniest part is looking for cotton clothing to wear--but with an eye to its potential future use.
