How much fondant do I need to cover a 10" 8" and 6" cake that are 4" high. I am making my own fondant and am not sure how much to make.

Thanks Sue

There is a really handy chart from Satin Ice posted on the Global Sugar Art website here

According to this chart, you will need about 5 pounds (4 1/2 by my calculations).

Also, what fondant are you planning to use? It sometimes depend on the fondant and how thin you roll it.

I made my own from a recipe on here that everyone says is very good. The recipe says it make 3 pounds.
Thanks for all the help.

One batch of MFF is enough fondant for two 6" tiers, two 8" tiers, and two 10" tiers. With some left over. But I roll mine to 1/16th an inch thin too.
