Heat transfer vinyl (HTV) is a type of material used for decorating fabrics. It comes in sheets or rolls and is made from a special vinyl that can be cut into designs or letters. Once cut, the vinyl is applied to fabric using heat and pressure, which causes it to adhere permanently. HTV is popular for creating custom clothing, accessories, and home decor items. It is available in various colors, finishes, and textures, allowing for creative designs. To apply HTV, a heat press or an iron is typically used, making it accessible for both hobbyists and professionals.
