Share a little about the materials, processes, and techniques used to create this cake This was my first attempt at air brushing, and what a project i chose! It is a fire truck for a gentleman retiring from the fire brigade after 46 years of service. It was 48cm long x 18cm wide and 20cm tall to feed 100 people. I took lots of photos of his truck to try and match it as closely as possible. I did have a couple of bleeds, but overall i was pretty happy with hard work (22 hours of it).
