The COSTUMAKERS general purpose zipper is a lightweight, closed-end closure for everyday apparel sewing. At 20 cm (8 in) in Butter, it uses a smooth nylon coil and bottom stop for non-separating applications in dresses, skirts, and pants. Sew with a zipper foot, keep the tape aligned as you stitch, and press the seam allowances carefully for a smooth-running finish to keep the tape flat and reduce snags.
