One of the easiest way is taking the foam-board tri-fold used for things like science fair projects.  You can decide if you want to add a lightweight curtain rod attached to the 2 outside "wings."

Hi, y'all! Can anyone recommend a puppet stage that you can easily disassemble. Not too large, so you could possibly carry it for school visits?
 
Thanks!
