Isn't it strange that we hesitate to tell about our 'frugal' sewing only to find out everyone is doing it? I'm drawn to the unbleached muslin just because it looks old and I can use any other colors with it in scrappy quilts. My mother always used sheets for backing in her later years. When she was younger feed sacks were used. As far as I can tell mother never bought any fabric for quilts - everything came from dressmaking scraps. I've been considering dying some muslin using Kool-Aid in a spray bottle like we did at Vacation Bible School a few years back. Think it would work? I know it wouldn't be solid but I'm curious to see what it would look like. Everyone knows Kool-Aid is almost impossible to remove from clothing.
