Upload the text or image file you want to Cricut’s Design Space, then select “Mirror Image” on the Cricut and print out the design on Cricut iron-on material. Use your weeding tools to remove all non-design areas from the iron-on. Cut out the design and place it on your sash, then use the Cricut EasyPress mat to adhere the design to the sash. If you used a metallic iron-on, wait for it to cool before peeling off the plastic backing.
