An easy way to add people to your cakes is to use push molds like the molds used for sculpy clay. I have a cookie cutter with the shape of a person that I use to cut out the person on fondant. Then I use the push mold for the face. I have a very tiny brush or you can use a toothpick for the features. You can paint on fondant with clear vanilla extract and gel food coloring. The hair can be made with icing and the grass tip or fondant.
