Cut out a few face shapes... then facial features galore. Noses, eyes, ears... you know, the kinda things you find on a face. An eyebrow can become a forehead wrinkle. Lips can double as a a haircut. You can then spend some delightful time creating funny faces, laughing at them & trying to to 'create' yourself.
If you love one, why not glue it in place... then even glue a magnet onto it & place it on the fridge?
