3/8" Seam Basting tape will make any sewing project faster and easier to manage under the needle! Our seam tape is a high quality, double-sided clear acrylic adhesive that will bond well to any of our canvas fabrics. It is ideal for sewing high end fabrics like Outdura. It will reduce sewing mistakes and even seal your seams making them stronger and more water tight! It is a must for double felled seams and bindings. One roll is 55 yards of seam tape!
