You will need:
Paper Bag (duh)
Markers, stickers, buttons, yarn for hair, construction paper
(anything you want to decorate it with, make people or animal puppets!)
I'm sure you all know the basic idea. Put your hand into the folded paper bag and the fold becomes the mouth.
Decorate puppets and put on a show!
Easy and simple way to have a puppet theatre:
Get a short shower curtain rod (the kind that pressure mount). Put it down low in a doorway and drape a sheet over it like a curtain.
Your child site behind it and holds the puppets above in view and puts on a show!
