Fuse the ribbon with a wood burner. You would need to know your loop measurements. It may make it a bit more difficult to sew through the middle. or if you could off center the fused parts just a little so that you could still get the creases and sew through them it might work.
Hope you are able to figure it out and will post pics (maybe even instructions..lol)
