Heat transfer vinyl (i.e. T-shirt vinyl, Iron-on vinyl) comes with a heat activated adhesive on one side. The other side has a clear carrier sheet that keeps the vinyl intact until application. All cuts need to be mirrored (or flipped) because heat transfer vinyl is cut from the reverse side. Easyweed heat transfer vinyl is compatible with all personal hobby and craft cutter machines (Silhouette, Cricut, Sizzex, etc.) and can be used in many applications including shirts, hats, shoes, bags or most anything that can withstand the application temperature.
