Sew‑in waistband interfacing that resists rolling and stretching to maintain a clean waist edge. The 38 mm width provides firm support for skirts and trousers while keeping a comfortable profile. Comes on a 28 m roll (1 1/2" x 30 yd) and is stitched into the waistband rather than fused, making it suitable for fabrics that do not respond well to heat. Reliable structure with a soft hand. Suitable for home sewing rooms, classrooms and retail kits.
