Making a TT cake for about 65 people. Probably 3 tier, with 3 layers each tier, like directions posted on here. What sizes of pans should I use to feed that many? 10, 8, 6? 14, 12, 10? 14, 10, 6? Not sure how to calculate this kind of thing and I can't find anything on here that I can understand.
Thanks!

Party or Wedding? The serving sizes are slightly different. You can go to www.wilton.com and search for the servings charts.
