Using the spacer wheel, slowly trace along the pattern. (Note: If you need to stop at some point, make sure to start again at the same distance of the small indentations the wheel is making, as these will be your guide for sewing.) Use the stitching awl to poke through all indentations through both layers of the stocking, making sure you're pushing straight down. (The spacer wheel won't press through to the other side, so this extra step will help keep your stitches straight.) With sewing thread and a leather hand-sewing needle, start a running stitch from from one of the top edges.
