Heat transfer vinyl (HTV) is the answer to your personalizing projects! Of all the garment decorating methods available, heat transfer vinyl is one of the least expensive and easiest to get involved in. HTV is either a polyurethane (PU) or poly vinyl chloride (PVC) material that comes on a clear carrier sheet. Siser heat transfer vinyl is available in a wide selection of colors and finishes such as glitter, flock, glow in the dark, and even patterns! Heat transfer vinyl is so durable that, when applied properly, will outlast the shirt’s fabric.
