After discovering the neon sign style for cookies, I wanted to transfer that simple, clean look into a pastel spring color setting. I tried by using a white background on the cookies, but it was not the look I was going for. However, when I painted the cookies with bright spring-y colors and used white glaze for the silhouette and detail lines, it matched what I was envisioning.

Just like with the neon sign style, once you get the background painted on, the decorating is super quick and easy.

Using a mixture of bright Americolor gels and vodka (or a clear extract like almond), paint the surface of each cookie completely.

Allow them to dry for a few hours.

Using white glaze, add the outlines and detail lines to each cookie.
There are no set rules here, so have fun with this!
P.S. I had to keep reminding myself that simple is better. :)
