One of the kiosks at the Liberty Bell Plaza in downtown Walnut Creek sells Folkmanis puppets (from Emeryville), and now there is a DIY puppet show stage and the Folkmanis kiosk will lend puppets so children can put on their own puppet show.
From the Liberty Bell Popup Plaza website:
Did you know that EVERY weekend in March, Popup Plaza is hosting DIY puppet shows? There’s a custom built stage available for kids (and adults) of all ages. Just stop by the Folkmanis Puppets popup and ask them about it. Folkmanis has puppets that they’ll lend you to put on your own show. What a great way to keep the kids entertained and take a break in the plaza!
