Create uniquely colorful apparel with Iridescent Heat Transfer Material. This is a specialty heat transfer material which gives a multi-colored appearance as light is reflected off the surface. Heat Transfer Material is a film material which has a heat-activated adhesive backing, so it can bond permanently onto fabric. This means it can be applied onto various fabric surfaces, such as t-shirts, jerseys, or bags. Great for creating customized apparel, Heat Transfer Material is a professional-looking material that creates high-quality projects. Heat Transfer Material can be loaded directly into a Silhouette cutting machine and does not require the use of a cutting mat. Heat Transfer Material includes its own transfer liner, so no transfer tape is required.
