This 2560 canvas, woven, fusible interfacing is used to add structure and reinforcement to fabric without stiffness. Made from mixed fibres, this high-quality interfacing bonds to fabric when pressed with heat, enhancing durability and providing a smooth, professional finish. Unlike non-woven interfacing, woven interfacing has a fabric-like structure, ensuring it moves naturally with your fabric. To use press the iron on step-by -step for about 12 seconds, using a damp cloth. Do not push. Washable at 40%.
