Use the Cricut Sportflex iron-on vinyl to create clothing. The vinyl is thin and flexible, making it ideal for sportswear and polyester or nylon fabrics. To process the vinyl with your Cricut cutting machine, there are just a few things to keep in mind: Place the vinyl 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 so that they are reversed. The machine will only cut the top layer of the vinyl, leaving the carrier intact. However, to ensure all settings are correct, it's a good idea to do a test cut first. The vinyl can also be used with cutting machines from other manufacturers.
