I found a recipe for the hard frosting to paint with and used it. The key to getting good color was to use plenty of food coloring so the colors would be vibrant. I stirred with a little plastic spoon but a straw would work. Everyone had their own themes for detailing the cookies and all of them were just perfect. The cookies can be hung at home just like my memories as a kid.
