After mulling over the design of the cake for a while, I decided it would be fun to sculpt the detachment's patch:
The first thing I did was scan the badge and use my copier to enlarge it. Then I set to work on coloring the fondant I would need. This proved to be harder I'd anticipated. I live on an island without a lot of access to cake decorating supplies. I wasn't able to get the fondant in the colors I needed, so I had to do the best I could with white fondant and food coloring. This resulted in the colors being more muted than I would have liked.
After carving out the shape of the patch, I did a quick icing job. I didn't have to worry too much about getting it super smooth or covering every bit of the chocolate cake since I was planning to cover it in a colored fondant.
Here's the final product:
I'm really pleased with the way it turned, I just wish I'd been able to get the colors more true to the colors of the patch.
