Just had a request for a 3d motorcycle. Not sure if I can pull that one off. I have seen lots of cool pictures of them, but can't find any directions or tutorials. Anybody have any ideas on how to do this ? I need to let her know ASAP if I think i can do it or not. I say NO WAY.

Anybody at all.

I made a motorcycle cake recently... look in my pictures.
First, I formed the tires and body from rice krispies and covered them. Then, I cut the rims and other various pieces from grey fondant.
The tires and body are attached together with toothpicks.The rest of the pieces are fondant and gumpaste. I was asked for a motorcycle cake and decided that it was WAY easier to make the road the cake and the bike the decoration... hope this helps
