This is the grooms cake for my cousins wedding (part two of the wedding gift). The design was inspired by a Charm City Cakes design. The original cake had post cards instead of interstate signs though. The interstate signs represent places that were important to the couple (where they met, where they got engaged, where they got married, etc.). The cake is done in buttercream. The "roads" are painted on with black airbrush coloring, and the hash marks are piped on. Interstate signs are edible images.
