I've seen various blogs that had ideas like this, either made of felt or magnets, and I knew it would be something my son would enjoy. I cut out a simple felt pumpkin shape, then a bunch of eyes, noses, and mouths.
My son kept wanting more scary faces, so he didn't appreciate my smiley face. I think it is kind of cute!
Tons of possibilities, lots of fun!
You can even make scary cyclops alien faces!
