Need advice!

I'm making a very big "present" cake, 6 layers (with each layer torted--so there will actually be 12 layers). Gonna be huge! Shall I put a cakeboard under the first 3 (6) layers so that when we cut it we will only cut halfway thru?

Who could handle 6 (12) layers????? This makes sense to me, but guess I never see it if it isn't a tiered cake.

Please forgive my neophyteness!

Every four to five inches of height should be boarded and doweled if you want your cake to stand well. So it just all depends on how tall it is. There are real thin multi layered torts that would not require doweling at all so it just all depends.

Thanks! Now I have a guideline!
