Designers have been experimenting with new techniques as they phase out old props and create new ones.
“We've used a lot of foam this year for new props,” Watham said. “We carve them using Dremel tools. We're moving away from chicken wire and papier-mache.”
While most of the new additions are being kept under wraps, organizers revealed there will be a Wizard of Oz-themed prop with a witch's foot sticking out from beneath, complete with a pair of red ruby slippers.
For Watham, the best part is the moment just before the gates open the first night.
“I love seeing the kids all decked out in their costumes,” she said. “The look on their faces is priceless.”
