We start by using the black icing as the hat, let it dry. You can either mark off the area of the snowman's belly and body area with an edible marker, or if you are good at free-hand you can just piped the icing straight on the cookies :) Use a white flood icing to fill the belly area and the face, let it dry.
Then add the snowman's face details. Pipe 2 black dots for his eyes and an orange squiggle for his nose and lastly a few smaller black dots for his mouth.
We also made a very simple polkadot Christmas Tree, all you need to do is put the red and cream polkadot icing on the green icing while its still wet. We use random sizes for the polkadots - see below.
These are the two different Christmas trees we made :)
