So, I insisted on getting exactly what I wanted, 4-tier cake, even though my wedding had only 20 people.
First of all, anything less than 4 tiers wouldn't look grand
Second, I have decided to go with narrow tiers rather than wide ones, so there won't be actually that much cake.
The layers were 2", 4", 6" and 8". Although bakeries don't really do 2" layers, I have insisted and I am glad I did. The cake turned out beautiful and very grand - even though it wasn't wide.
Colors of the wedding were Yellow and some accents of Royal Blue.
Oh and if you are doing wedding in Hawaii - pick the bakery I picked - Aloha Bakery - just mind-bugging... SO tasty! All guests actually had at least 1 piece (some 2-3), even after the dinner!
