I loved the Campfire Story Center that Erin Drew at Ms. Drew in the Library shared with us! I took the suggestion from Ms. O to add little orange lights (widely available in October).
I set up the campfire outside our reading tent, with this $25 Vandring Spar rug from Ikea.
You can see here how I set up the center. I've got a sign in an acrylic stand, a cardboard fire, painted red, orange and yellow, with a strand of orange lights hung loosely over the cardboard. I tried putting yellow and orange tissue paper over the lights so you wouldn't see the wires and bulbs. But the tissue paper heated up very quickly, and it seemed too risky.
The "fire" sits on a large black circle of butcher paper (kindof like a fire pit, if you squint from real far away), and one real piece of firewood. I've also got a bubble tote with some books in it (in case students didn't check out books of their own).
This center has added some real reading fun to our library. I hope you'll try a campfire center in your library, too!
