Westalee High Shank Ruler Foot with 12" Arc Template. The Westalee Design Sew Steady Ruler foot is designed to enable quilters using a domestic sewing machine to quilt with rulers and templates to create beautiful quilting designs. The ?fence? of this foot rides up against the Westalee ruler template, creating beautiful free-motion quilting motifs. Use a Westalee ruler template and both the size and the shape of your free motion motif will remain consistent while you quilt. As long as your needle is positioned in the center of the Ruler Foot, your stitches will form exactly 1/4 inch from the edge of your template. For the best free-motion experience, we highly recommend you also use a silicon quilting mat, extra-long staple quilting thread, a quilting needle, and quilting gloves. Do not use your needle down function while the presser foot is lifted. The Westalee Ruler Foot comes in high shank, medium shank, low shank, and special high shank. The stable tape is an aid to reduce ruler slip and helps grip your quilt top. Just cut into smaller lengths and peel the adhesive backing to stick onto your rulers. Amy recommends not applying as a long single strip as this may cause the ruler to rock from side to side.
