I have been asked to make a fishing cake for a little boys birthday next month, so I wanted to start asking around now...Does anyone know a good way to make realistic fish scales? My thought was to take a decorating tip and push that into the cake to make the "half circle" like scales..does that sound reasonable or am I way off?

I did a cake last year http://cakecentral.com/gallery/1684783 and that is exactly what I did!
Good luck.

I remember seeing that cake it looked great!! THanks so much!

I did the same on my fish cookies.
