I found some appropriate images and drew small templates to fit the top of a standard cupcake. The templates made it easy to cut out the fondant. I let the cut pieces dry overnight to firm up, and then I used food-safe markers and luster dust to decorate each topper. I brushed the boot lightly with a dry brush dipped in luster dust (I dipped it in and then tapped it on the side of the container to get just a tiny amount). The star and horseshoe needed a deeper color and thicker coverage, so I mixed the luster dust with a few drops of vodka to make a paint. (Luster dust is not water soluble, but the vodka will evaporate - no worries about feeding it to kids!)
The cupcakes looked adorable and fit the theme perfectly. Happy birthday, Li'l Cowboy!
