Growing up, we had a doorway puppet curtain that was really similar to this one (only difference is that ours hung using a tension rod), so when I saw this DIY Puppet Theatre it immediately appealed to me. We used to spend hours putting on puppet shows growing up.
My mother made puppets out of felt with a different character on each side.
I definitely want to try to recreate this one day.
