Wow, you do precise work. I really haven't done English paper piecing much. I'm not on this site much due to time. I have a Corgi and a Lab and my best friend raises Bichons in Texas. (My labs tolerate them.)
oh, and the fabric exchange isn't near as active as the EPP group you joined. Some really active groups I've joined that have the best conversations are Karen's UFO group and the Around the Quilt Frame groups. YOu will learn all kinds of random things, not just about quilting either, when you're sitting around a quilt frame (so to speak).
