I've just done a two part online workshop called Machine Wrapped Cords. It was a free workshop through this website: http://edu.creative-textile-and-quilting-arts.com/
I had made some a couple of years ago in a workshop with Faye Twining. Here's some photos of both lots. It was great fun, and makes a change from making quilts. There were a few other techniques covered in the free class that I haven't tried yet. It was definitely worth doing!
