At PIQF there were LA's set up with varigated threads. Innova had black fabric with light metallic varigated. All the colors showed beautifully for the demo. Another had a light fabric with a varigated from white to dark. It was very interesting as it looked like it was quilted about 6 inches, then a skip, lot's of movement.
Is there a varigated thread with ~15" between changes? What brand? I'm trying to teach FMQ with a change in the pattern for every color change. 1 1/2 " is just too fast.
