Bride wants cake to look like this.... http://www.peggyporschen.com/Tiered-Cakes/cake-details.asp?offset=-1&id=180

looks like 3" tiers alternate with 6" tiers.
a) How do i achieve the tall tiers...do you think 3" and 4" could pass and look similar?
b) even if i use foam board under the 4" tiers, it wouldnt be as pictured.

any tips appreciated plllleeease urgent. its for this weekend

Honestly, I don't think 3" and 4" would be enough of a height difference to get the desired look. 2" and 4" might work, though. How many servings? What size pans are you planning on using? I think that would make a difference in determining how tall your tiers would need to be.

Beautiful cake, btw. I'll be anxious to see your version of it!

I think the cake as pictured is 2 and 4" tiers (or maybe 2 and 5"). But um... how many people are you needing to feed? Seems like awful short notice to be deciding on cake sizes

I would not use 3 and 4", they are too close and will look more like a mistake than a design element.

You will need to make the appropriate heights of cake, don't rely on extra boards to do the trick.

Thanks for your input. the bride has been changing tiers even this week. sad, but true.
