I bought these tiny jars a while ago and I couldn't think what to do with them, and then I got the idea to put some tiny characters inside of them and make them into christmas tree decorations. (They are very small, the jar opening is about 10mm) I think that next time if I made more I would use jars with a larger opening! That is why the snowman has somewhat stumpy arms haha!
I made the characters out of white Milliput and then I painted them. Milliput is ideal because it's air drying so it would dry in the bottom of the jars to create the snow, and its super hard so it is easy to paint.
