Use one color or layer multiple colors to personalize everything from sports team wear t-shirts and jackets to bags aprons scarves and hats. You can even customize home décor items such as pillows blankets basket liners and wall hangings. Cricut Iron-on sheets are made up of two parts. The film is the actual material that will be ironed onto your project and the liner is the carrier sheet that holds the design in place and protects your iron during the application process.
