I made these cookies as a gift for the people at Mohonk, a resort and nature preserve in New Paltz, New York.
To make the logo, I first drew it on AutoCad, which is an architectural design program that I use at work. I then printed a bunch on one piece of paper and placed it underneath a sheet of acetate paper, which was taped onto a cookie sheet. From there I piped over the template with royal icing, painted the designs with luster dust, waited for them to dry, and carefully lifted them off the acetate using a small offset spatula.
I applied the logos to the cookies when the green icing was still wet.
