BALTIMORE (WJZ) — The Mid-Atlantic’s largest holiday-themed festival kicks off in just one day. We are talking about the Festival of Trees, of course!

Mary Bubala has a behind-the-scenes look at what it takes to design a tree.

It’s a three-day extravaganza of holiday trees, lights and activities. There are toy train gardens, craft boutiques and holiday goodies. All the fun and creativity support the Kennedy Krieger Institute, and it’s become an after Thanksgiving tradition in Baltimore.

“Everybody knows they are going to the festival Friday morning or Friday afternoon or Saturday and, you know, people are here for the whole day,” said Lainey LeBow-Sachs.

Some of Baltimore’s most talented designers donate their time to create trees of art that are for sale to the public. People can also buy hand-crafted gingerbread houses as part of the fundraiser.

WJZ is entering three specially-crafted gingerbread houses. There’s the house of Denise and Vic, the house of Don and Marty and the house of Kai and Mary. It’s all to help raise money for Kennedy Krieger.

Festival of Trees organizers say the public has been so generous.

“In the last 22 years, it’s raised over $12 million,” said LeBow-Sachs.

It all starts on Friday.
