The girls love all things crafty. We've recently entered the world of markers, glue sticks and scissors. Em is fairly adept at cutting. Allie and Anna easily become frustrated and give up. We do keep the scissors and glue out of reach when the girls are not being supervised and luckily, we have had no incidents.
The girls all say that they want Tangled hair so I doubt that they would cut their own hair. We still supervise though.
They also LOVE activity books. Em spent approximately half of the weekend working in her jumbo size Hello Kitty activity book. Anna is hysterical because even though I know that she knows what to do, she still asks, "What do you do on this page?"
