Ruffler #86 specializes in gathering and pleating fabrics with variable settings for both pleat depth and gathering frequency. You can create pleats with every stitch, every 6th stitch, or every 12th stitch, and even sew without pleating by setting it to 0. The special gathering blade catches fabric with each needle movement, resulting in neat gathers and pleats for home furnishings or garments. Additionally, you can easily adjust the pleat depth using the adjusting screw for precise control.
