Cynthia England is a talented quilter who presented her technique at our guild's quilt show last year, and I finally got around to studying her website only a few months ago. Now I've noticed that she has very detailed demonstrations of the technique on youtube videos! http://englanddesign.com/content/video-demos-0 I know her work has been mentioned on this board before, but I had not noticed mention of the videos, which are quite helpful.
Check out the rest of her site as well as the videos. There's a lot to see, and her designs are beautiful works of art! http://englanddesign.com
