No Show Embroidery Backing (1.5 oz.) Soft, sheer, stable, and translucent nylon-reinforced cutaway backing. Specifically designed for left chest applications, eliminating the backing from showing through the garment. Ideal for lightweight, light-colored fabrics – keeps outlines on track when hooped in with your knit fabric. Can be used with a medium weight tearaway for added stability.
