This activity couldn't be simpler. You only need a handful of supplies you probably already have laying around your house.
You'll need :
an empty toilet paper roll
face stickers (or draw a face if you don't have stickers)
The instructions are pretty simple draw face, slice some hair, and then give safety scissors to child and allow child to give a "hair cut" to the person.
My four-year-old had a lot of fun with this activity. Originally I had only made one person to see if she'd like it I ended up making quite a few more. I like this activity because it allowed her to cut hair without actually cutting someone's hair...or a dolls hair...or her sister's hair.
