I am having trouble trying to figure out a tier combination for 150 servings or around there. Since I havent been in this long, I dont know what tier combos look bad together and I dont want to give them a weird combo. The only two I have come up with so far and they are not that good i dont think, are 8, 12, 14 which totals 144 but that might look weird, dont know, and 6, 8, 10, 12 which only does 130. HELP! Its tonight and I want to be able to give you a few options for tier combinations that serve around 150. THanks!

Have you checked out Earlene's serving chart? She has done some of the combo footwork for you.

How about a 14", 11", 8" and 5"? Should come pretty close and you'll have a nice 1 1/2" around each tier to add decorations.
