I am making a 16th birthday cake for a boy and have not been given a "theme" (mother says make whatever I want, just make it boyish).....All I have are the colors from the invitations, so Im guessing that I should do a design of some kind and not a perticular "topic"...Anyone have any ideas???

What about doing a car?

Do you have any clue as to what his interests are?

Driver's License or Car
WII or Playstation
Sports - BBall, BaseBall, Football
Music - iPod, guitar
Movies - Marshmallow Popcorn

If not, do a cake with just the corresponding colors for his invite.

Mothers doesnt really want a car and as far as his interest....she only said well he used to like....but doesnt anymore.....sigh

"Happy Birthday" or his name in graffiti
Shutter glasses
ball cap
skateboard
city skyline
slice of pizza or other fast food
Rubik's cube
