Heat Transfer Vinyl Sheets is a special vinyl polymer that can be used on specific fabrics and materials to create designs and promotions. It is roll-shaped or sheet-shaped and has an adhesive, so it can be placed on a substrate for cutting, weeding, and heating. The heat transfer vinyl is made in one color and is also available with special options like graphics, shimmer, swarming holographic, glowing in the dark, reflections, and 3D powder puffs.
When working with heat transfer vinyl, the shiny side of the material always goes face down for cutting. This shiny side is called the "carrier." It covers the face (the colored side that will face out on the garment) of the HTV and holds the cut pieces in alignment during cutting and applying.
Heat transfer vinyl is, of course, made out of vinyl. However, iron-on transfers include paper and transferrable ink. When you apply heat to your custom HTV design, the entire design transfers onto your desired item. With an iron-on transfer, it's the ink that sticks to your piece
