Place your bauble string side down in an egg cup or something similar. With your fingers put some paint on your entire finger and then press against the bauble. Don't over-paint your finger, as it will take forever to dry.
Put a single line down the bauble, or numerous lines of your finger around the bauble.
Entire finger print for Snowman, or dot for Reindeer
Once dry give the snowman a top hat with permanent marker, some eyes, a triangle for his nose and a smiley face. Place 3 dots down his tummy for buttons.
To make a reindeer instead, just do a thumb print, rather than a whole finger. Draw some antlers and a face with permanent marker, you can do this multiple times around the bauble. There are no rules on this one, except to have fun, and laugh at each other's designs.
