but I am trying to see if we are just way off in our pricing of wedding cakes. How much would you charge for this cake, assuming it would be covered in fondant and using RI to pipe the design, made to serve 150?

I can't figure out how to post the image here, so it is in my photos, first picture, the one with brown piping and blue ribbon.

it's a farily simple design, i would charge my standard pricing and have the bride provide the ribbon. (I would tell her how much ribbon i needed because a lot of people can't figure out how much ribbon it takes to wrap AROUND the cake)

How to figure ribbon requirements:

$487.50 for fondant. It serves about 150ish?
I know I'm on the lower end, but that's the going price right now here- $3.25 for fondant.

Well, maybe this is a better question. I know price is very dependent on your area and all that, and you really have to figure out how much you want to make over and above cost of materials and your pay for your time and skill. So I guess a better question is: how do you determine how much profit your business should be making off of a cake like that?
