I don't know if anyone else has heard of this... though I suspect they have since I'm usually the last person on the planet to know about stuff (or at least that's how it feels sometimes).
It seems the string quilt is a big deal these days. I found a tutorial about it here http://quilting.about.com/od/quiltpatternsprojects/ss/string_piecing.htm
It seems pretty simple. I'm going to try it out and let you guys know about. ^_^
