How many gum paste roses do I need for a 3 tier wedding cake that is 10 inch round bottom, 8 inch middle and 6 inch top tier?

286.

Sorry, I was just joking and now I feel bad. We need a little more information before we can help you.  What kind of look are you going for?  Do you want a few on each tier, a cascade down one side or . . . . ?

Uh, haha, I think jgifford might possibly be pulling your apron strings...what a character! If not then she must have a crystal ball or be a mindreader or math genius or something...

lorilyn12, was that a serious question or for fun? If serious, we would need to see the design you are trying to do or what you plan to do with the roses and how large each would be to do any kind of "approximation" of an estimate.

Is there a photo that we can see of the kind of arrangement you're looking for?

Jgifford - I don't know why but your second post was not showing on my phone when I made my post on the thread.
