I need help desperately! A lady from church wants me to make some cakes; she needs them to serve from 150-200 people.She wants 2, 9x13, 2, 14", 2,10" and 2, 8".My round cakes never stack right, can anyone please tell me the proper way to stack them? She wanted me to tier them, but I'm not sure even how to do that either. Any help will be appreciated.

Here is a link to Wilton's "How To's" on cake construction.

I make a 14/10/6 (2 layer each) for 100 guests. Are your 9x13's one layer or two? I'm thinking those sizes are going to be tight for 200 people.

Here's the Wilton link to servings per size: http://www.wilton.com/wedding/cakeinfo/cakedata.cfm

Here's a link to my website showing how to cut a cake to achieve the Wilton servings (I actually get about 10% more servings when cutting this way): http://cateritsimple.com/_wsn/page19.html

She wants them with 2 layers, do you think that will be enough? I hate to come up short.
