I have an inquiry from a bride asking me to do a 3-tier, 10-sided wedding cake! She wants the tiers to be 12", 8" and 6". Is this even possible and if so how??

Thanks for any help or input. I'm stumped.......

i say make square cakes in 14", 10" and 8" and cut the sides to make the ten sides. Start by making a stencil of a 12" ten sided cake you need, lay it on top of the 14" square cake and cut away, do the same for the 8" and 6". thats what I would do!

i don't know that all the angles will show after icing, but here's some reference

If I did one of those, it would end up looking like a round.
