Decorate cookies. Using the candy corn template draw a horizontal line 1 in. from the pointed end, then draw another horizontal line 1 3/8 in. from the first line. This should leave you with a 3/4 in. stripe. Place a flat piece of parchment triangle over template. Starting at bottom of pattern, tap parchment bag to sprinkle sugars to cover parchment covered template in this order: yellow, orange and white. Use the spatula to level the sugars.
Spatula ice cookie smooth, place cookie iced side down onto sugars. Press down gently. Repeat.
