Hi, make some labels out of pastillage or flower paste so they are hard and edible images are probably the best as be the cleanest looking. You could paint pictures on if you are confident with painting. HTH
I made a luggage cake and used edible images. It was my first time. First I downloaded the flag or logos from some places my MIL have been, put them all in one page and took it to a bakery supply store that have the printer. They worked perfect!!!
