1 part white glue
1 part shaving cream
Glitter (to "taste")
Couple drops of peppermint extract (optional)
Mix together well. We used a popsicle stick to stir it up. Apply with brushes or craft sticks. It doesn't SPREAD very well because it's so puffy. Your best method for application will be a dabbing or dotting brush stroke.
We combined this invitation with a set of washable markers. This way older children could draw their snowscape first and then add the layer of "snow." For younger children, our parents and instructors helped draw while the children added the snow to the snowman or the trees.
