Review on 11 ft. Roll of Craftables UV Sensitive Heat Transfer 🎨 Vinyl for Fabrics - Light Blue, Color Changing Iron On Vinyl by Angela Rodriguez

This HTV is easy to use. Cuts well and is easy to apply. Yellow is the most difficult to depict using ultraviolet light, but once exposed to natural sunlight, it quickly turns yellow. The color fades quickly when you return to the room. Design wise, I've found that when you wear this vinyl over a white shirt, it stands out with a slight yellow cast (no UV light). However, if it's in a design surrounded by another color, you won't notice the hue at all and it will appear white until you step out into the sunlight.
