Hint: You only need one color and one consistency for these cookies. I use 20 second icing. I outline the cookies, let them dry for a few hours and then paint them with "old gold" luster dust. I mix my luster dust with a "little bit" of vodka. I give it two or 3 coats to get the look I want. Just remember to let each coat dry before painting the next one.
Then I flood my cookies with the same 20 second icing.
To get the pretty green color, I used Americolor "Leaf Green" with a touch of "Sky Blue". Sugarbelle has a now famous tutorial for obtaining the perfect consistency for icing your cookies. I posted her video below. Her tutorials are very helpful. I follow her blog and facebook page on a daily basis!
