Sewing a decorative wavy edge with the Corded Wavy Edge Foot is easy. The curvy, softly ruffled edge is a perfect finish for bridal veils, figure skating costumes, ballet skirts, crafts and more. Note: For best results, use fabric with stretch. For fabric with no stretch, cut on the bias. How to use: Set the machine for a 3-thread rolled edge. Snap-on the Corded Wavy Edge foot. Insert a 0.3mm nylon fishing line (or similar) into the opening in the foot. The fishing line will be covered by the rolled edge. Start to sew slowly. Make sure the fishing line is hidden in the rolled edge as you sew. Tip: * 40 wt. rayon embroidery threads in a contrasting colour in the upper and lower loopers will give a shiny colourful edge.
