I made these potato shells using egg cartons- the ones made of paper pulp.I am using this as a teaching aid for colous.
As I show her each color I place a bottle cap of the same colour as a hat for the potato head. My 2 year old found this really interesting, so much that the day I made it she took these potato heads to bead instead of her favorite soft toys :)
This is how I cut the egg carton and have glued together the 2 parts. I then painted them with acrylic colours. And then used a ball point pen for detailing the facial features. You could also use googly eyes and may be some black wool for hair.
