Foil is a specialty option for apparel decoration. Your design is first cut with a plotter in a special glue and applied to your garment. The foil is cut to the shape of your design and applied onto the glue with a heat press. The combination of heat and pressure seals the foil before the excess is removed. Foil is much thinner than glitter vinyl. Foil helps bring your design to life and make your prints really stand out.
