You know the ornaments where the students put white paint on their fingers and then grip a plain colored ornament to make a group or family of snowmen? What kind of paint and what kind of ornaments do you use? I was thinking the liquid acrylics/craft paint like at Michaels - would that be right? And I was wondering if the shatterproof ornaments work. Please help!

Thank you.
Oh, and then how do you make the finishing touches - do Sharpies work?
