I use mine because it saves on the budget. I tend to be quite frugal so I try to use every bit that I can. I like my quilts to have some color boundaries/structure so haven't made an "anything goes" quilt yet. My avatar was made all from scraps, but only red, yellow, green and blue on the white background.
wraez, I really like your avatar. It mixes things up more than I've tried before, but I like the nine-patch look. I'll have to try one of those.
I also use mine for applique a lot.
