I've filmed several videos featuring my new 4-N-1 machine quilting ruler.
We're not professional videographers, so I'm sorry that it's a bit out of focus, but I think you'll get the concept and hopefully find a bit of inspiration.
My machine quilting is done on a Gammill 22" Long-Arm Quilting Machine.
