I love your puppet theater! I wish I could have used your design.
Years ago I made my grandchildren a free standing puppet theater out of wood and hand puppets to go with it. Unfortunately, they only had a very large archway in which they could have their theater. The other advantage was it could be set up in any part of a room. But, what a chore to build. I started out to make the hand puppets but then realized they needed a theater too. They really liked it though so it was worth it. My pictures are on an external hard drive. If I can get the time to get at it I'll post some pictures.
