in this video, we start with an already iced cake, which I showed how to do in the 3rd video. This video shows 2 ways to trim it (tucking/cutting it off).

In order to cover a cake, you need to ice it first, so the fondant sticks. It may help to have a turntable, but a plate is fine.

This video is about coloring fondant 3 ways. With gel color, liquid color, and marbling.

This video is on making easy fondant with only marshmallows, icing sugar, water, vanilla and shortening.
Fondant is not mandatory for cake decorating, but looks beautiful on a cake.
It is also used for covering cookies, and modelling decorations.

WHAT YOU NEED:
4 1/2 cups mini marshmallows
2-3 Tbsp water
up to 4 cups powdered sugar
1 tsp vanilla
1/4 c shortening
