I took the Scrap Therapy class a few years ago and the teacher's theory was that scraps cost just as much as yard goods....so if you get them into useable shape.....your quilts cost you nothing extra. It took me a month to drag out all the boxes and bags of scraps (I did this while watching TV) and iron and cut. Since then, I'm made 13 Scrap Therapy quilts for my charity group.....and those are just the ones that I didn't buy extra fabric for the borders and bindings. It's true....if you've been quilting for awhile....the amount of scraps is astronomical.
