Sometimes you get a big idea. And sometimes you get to make that idea a reality. This year my department was given funds to create big family programming, and I got the chance to build my idea: a giant cardboard maze that would encourage caregiver-child interaction and create a memorable library experience for customers of all ages.

The Event

A families-only Harry Potter-themed after-hours party kicked off the maze, which measured 75’ long, 15’ wide, and 6’ tall, and sat smack-dab in the middle of the main hall of Denver Public Library’s Central Library. Customers lined up out the door to wait for their turn to explore the maze. A staff member at the maze entrance spaced out families in two minute intervals to avoid traffic jams. We also hid the four Hogwarts house crests inside the maze. Kids were given maze passports, and when they found a crest there was a staff member dressed as a Harry Potter character waiting to stamp their passport. This allowed us to have staff in the maze in case of emergency.
Other party activities included pin the sock on Dobby, magic wand decorating, and, of course, tasty themed snacks. Having a theme for the maze wasn’t necessary, but it did make the event easier to promote. Plus, it meant lots of kids came dressed as their favorite Harry Potter character.
After the party we left the maze up in our main hall for a week so customers of all ages could explore the maze. In addition to walking through the maze, customers could look down from the 2nd and 3rd floors to plan their route or watch others go through the maze.

Construction

I’d seen pictures of cardboard mazes online (thanks, Pinterest!), but I couldn’t find anything tall enough for adults. My goal was to create something that children and their caregivers could explore together. I wasn’t able to find any instructions online, so I decided to figure it out on my own. This process included lots of brainstorming and several mini-maze mock-ups. Here’s a list of things to consider, based on my experience.
- Safety and Space. Measure your space and learn about your library’s safety rules and regulations. I met with the security, custodial, and facilities departments to get their input. From this meeting it was decided that we would have a minimum of 5’ of space on all sides of the maze. We also decided to include a third side entrance/exit to the maze in case of emergency.
- Design the Maze. I had never designed a maze before so I was grateful to find some wonderful online resources. Jo Edkins has great info about maze layout and design and the tips on avoiding bottlenecks on Amazeing Art were useful. I found it helpful to first determine the entrances/exits and then divide the space into three “mini mazes.”

This is the kind of project that requires teamwork and delegation, so it’s important that your paperwork is detailed and clear. Here’s a copy of the maze layout.
- Purchase Materials. I purchased my materials from the following companies:
- Home Depot – 36” x 36” x 36” cardboard boxes
- Home Depot – packaging tape
- Reliable Paper – 36’ x 72” cardboard sheets
- Staples – 8” zip ties
- Purchasing Considerations.
- Some companies require a minimum number of a particular item per order.
- Freight shipping can add a significant amount to the cost of materials.
- Height of your loading dock. Ours is very low, so this impacted delivery.
- Talk to a representative. I was able to get more accurate quotes and ultimately a

- Prep as much of your maze ahead of time as possible. Call in your volunteers, friends, and family! Cutting and labeling our boxes required approximately 20 hours of prep time.
- Putting It Together. It took us approximately 10 hours with 5 people working steadily to put the maze together with the prepped materials. This includes the 5 hours we used to construct 45 maze units the day before the event and stored them in our storytime room. The day of the event we had another 5 hours to assemble the other units and zip-tie them all together. Check out the step-by-step Maze Construction Instructions.

Conclusion
Yes, this maze took a ton of planning and staff labor, but it was worth it. From a numbers point of view, it was gratifying to have 300+ people come to the after-hours party. But it was even more satisfying to see the smiles, hear the laughter, and watch our customers find joy in exploring the maze. The maze was also an entry point for staff-customer interaction and encouraged customers to visit our 2nd and 3rd floors to look down on the maze. In short, it was an unforgettable library experience!

WOW! I am in utter and complete awe of this. Great job to all who were involved!
Amy Seto Forrester
Thanks, Rebecca! I have wonderful colleagues who really pitched in and trusted that it would all come together. It couldn’t have happened without them.
Kary Henry
That is truly awe-inspiring! I love everything about this!
Amy Seto Forrester
Thanks, Kary! The maze made me smile like a fool every time I saw it or watched someone interact with it. 🙂

Wow! Super duper! Just about the coolest thing I’ve seen in ages. Sharing on FB and twitter. You guys rock!
As you may know, I create lots of maze books (and a couple interactive maze apps). Here’s a page on my website that shows how to make a geometric maze (on paper…not in 3 dimensions, like your extra fantastic maze!). http://www.roxiemunro.com/make-a-geometric-maze.html
Alia Shields
Wow!! This is such a cool idea and I love the Harry Potter tie-in. I guess it could also be a great activity for a Maze Runner program.
Erin
What??! Holy wow! This is so awesome (A-maze-ing…couldn’t help it..)
Thanks so much for sharing. What an inspiration!

Four + years later and you inspired us. We built a 24 x 42 foot maze at Eugene Public Library for #HarryPotterBookNight 2020. We used a lot of your instructions for building on a grid with 3x3x3 foot boxes, and panels. Our maze stayed up just one night, but the memories will last a lifetime!! Check it out on our social media. Thank you for the inspiration and the instructions!!!
