Use these non-slip paddles to keep your quilting area flat while using a stationary quilting machine. The two control knobs provide a comfortable free-motion quilting experience. Guide the quilt sandwich for free-motion quilting by placing the paddles on either side of the machine needle while applying light downward pressure. The special non-slip material on the base ensures that the fabric moves without the layers shifting. To maintain the non-slip properties of the base fabric, use sticky tape to remove lint and stray threads.Overall size of each paddle: 8.5″ x 3.25″ x 0.5″
