Use the Cricut Sportflex iron-on film to create clothing. The film is thin and flexible, making it ideal for sportswear and polyester or nylon fabrics. To process the film with your Cricut cutting machine, there are just a few things to keep in mind: Place the film with the carrier side down on your Cricut StandardGrip cutting mat. Then select the images and size you want to cut. Remember to mirror the images before cutting. The machine will only cut the top layer of the film, leaving the carrier intact. However, to ensure all settings are correct, it's a good idea to do a test cut first. The film can also be used with cutting machines from other manufacturers.
