Siser Holographic Heat Transfer vinyl adds color shifting dimension to any project. Holographics cannot be layered with other Siser vinyls. Best to use with Silhouette Cameo or Portrait, as well as the Cricut Explore, Maker, or Joy. To Use: Insert into the machine with the carrier sheet (shiny side) down. Use your software to mirror the design you wish to cut, and cut with your preferred settings. Weed or peel excess vinyl. Preheat the garment for 2-3 seconds. Press for 15 seconds with medium pressure at 160℃ or 320℉. Peel off the carrier sheet cold.
