I had fun making this cake and thought I would share how I made the little witches. They really were quite easy to do so you don't need much skill to do them.
Roll a tiny bit of green fondant and glue on for the nose.
Glue the hair around the head. This is where you can trim the hair piece to fit properly on the witch. Don't worry about the bald spot, the hat will cover these.
Glue the cone onto the base of the hat. I used edible markers to draw the mouth and eyes. And there you have it...little witches. These can be used on your Halloween cakes and are small enough to go on top of cupcakes as well.
