Not on mine. I used double edged carpet tape to attach to pole, then put duct tape over that. I'm doing mine like Susan Schambers does hers. Susan uses velcro to attach the leader part to the qult leader. You stitch the quilt leader onto the quilt by basting.
A speed control controls the speed of the machine, so you don't go to fast or to slow. A stitch regulator keeps stitches even if you speed up or slow down.
