This project gets high marks in the easy-peasy category. The kids did most of the work, I just traced mustache patterns and tied knots. It also get high marks in the very-silly fun category, making it an all-around great activity, highly recommended.
What you need:
mini hole punch
elastic beading cord
magazine clippings of hair (or for littler ones, I used craft foam)
Trace the mustache shapes onto the magazine clippings or the craft foam and cut them out. Punch holes and tie the elastic cord through the holes. You will need to make several knots and then trim the ends so they don't tickle your nose.
