Westalee Design's Spin-e-fex Snowflake templates are so easy to use. The etched markings are easy to see – Westalee’s unique Key Gate System allows you to place the Ruler Foot inside the template and then close the opening. This prevents the template from expanding as you stitch and does not leave you with a flat spot in the stitching where you stitched past the opening. For low-shank ruler feet. 2 piece set.
