The Clamp-On Stitching pony has leather covered jaws to gently yet firmly grip your leathercraft project while stitching. It has a spring loaded knob to easily open and close the jaws to clamp on to your stitching project and magnets to hold your needles. The adjustable joint allows for angling of the stitching project for ease of use and comfort. It clamps to surfaces up to 2-1/2" thick. Makes stitching a dream.
