You get the template shown with cut out "tabs" along the top and bottom of the opening. Included are 2 sets of uppercase letters: 1" and 2". You just use scissors to cut off the letter you need and then insert the plastic into the tabs. The letter is held into place so you can even work on a vertical surface (like the side of a cake). You can overlap the side edges of the letters, as shown above, to shrink the spacing and avoid getting color on your project.. Stencil is made out of durable, 10 mil food-grade plastic.
