Prym 968235 - Seam tape interfacing
Iron-on seam tape interfacing to reinforce heavily-stressed seams such as armholes, neck openings, shoulder seams, and piping button holes. The 10 mm-wide seam tape is ironed on with light pressure on the cut portion's seam contour and provides improved stability there. This prevents the fabric from warping when moved under the sewing machine's presser foot. The easy-care and environmentally friendly seam tape is composed of 50% viscose and 50% cellulose.
It can be washed at up to 40 degrees, dried in the dryer, and it can be ironed. The card contains 10 m of iron-on seam tape.
