Wow......a single-colored cookie.
If you only knew how hard that is for me. :)
But in this case, making it golden made it worth it.

There are MANY butterfly cookie cutters, so that shouldn't be hard to find.
Here's the one used in this project.

With gold 10-second glaze (only ONE color to mix up!), outline and flood the butterfly wings.

Allow the glaze to dry for about 30 minutes.

Add large round balls of glaze down the center of the butterfly to make the body.

Outline the wings with a 1.5 PME tip.

Add designs to the wings as desired.

Once the cookie has dried overnight, make a mixture of gold luster dust and vodka,

and paint all over the surface of the butterfly.

Beautifully simple.....
