I know this probably sounds really amateur but how do I go about stacking three cakes. I was going to do three Double layer cakes but I don't know how to support them. I'm supposed to be doing the three sheet cake sizes. I didn't know if that would work out. I see most tiers are circles or square.. I really need some help Please!

I've never seen tiered rectangles but that doesn't mean it can't be done...

Good luck!

You've gotten great advice already, but a great resource is the SugarEd dvds, www.sugaredproductions.com, they go through a very stable way to stack!!

Thank you very much! You guys are very helpful!
