3. Put paper under and trace a template. (Note, this will create a template for future koozies. You could buy thin foam if you don't have more koozies.)
4. Cut out the template.
5. Place it over the fabric and pin in place. Cut 1/2" further out from the edge of the fabric.
6. Remove the template and pin fabric to the foam. Be sure to pin wrong side of fabric to right side of foam and center the fabric over the foam.
