My first attempt at the finger puppet theatre was made from a cereal box. This one at Weird, Unsocialized Homeschoolers (best blog name EVER by-the-way) was my inspiration. Prototype #1 was a disaster. And it was our only empty cereal box.
I tried again with a shoebox. It’s much easier to fit adult hands comfortably into the theatre and I used velcro to hang a piece of felt for the backdrop. And when we are done playing we can store the puppets away inside. Kept the nifty paper curtain idea.
