Lay your triangle 1 template on cardboard. Extend side A to 12 1/4 in (31 cm) on side B to 10 3/4 in (27.3 cm). Add a third line to complete the triangle, and cut the piece out.

Lay the triangle on cardboard and draw around it to make an identical triangle.

Make a 1 1/2 in (4 cm) cardboard strip and draw around it to add 1 1/2 in (4 cm) tab outlines to all three sides of the triangle.

Cut out around the tab outlines of the triangle. This triangle will be used for your first triangle 1 tile.

Use your triangle 1 template to mark a straight line across the corners of the triangle. Cut along these lines. Repeat steps 2-5 to make 30 triangle 1 tiles.

Now, lay the triangle 2 template on cardboard. Extend both sides to 12 1/4 in (31 cm) and join them up. Then, cut out the triangle and use it to repeat step 2.

Use the cardboard strip from step 3 to add tabs to the triangle, then cut off the corners. Repeat steps 6-7 to make nine triangle 2 tiles.

To make your square tiles, draw a square on cardboard with lines that are 12 1/4 in (31 cm) long.

Use the strip from step 3 to add tabs to the square. Use the triangle 1 template to mark and cut the corners. Then cut off the bottom tab. Repeat steps 8-9 to make nine square tiles.

Score along the tab lines of all three sets of tiles. Then fold along the score lines to finish making the tabs.

Project step photo 2


Arrange five triangle 1 tiles into a pentagon shape, so the tabs on the shorter sides meet. Use strong tape to fix the first two together.

Project step photo 2


Secure the other edges in the same way. Then repeat step 11 to make five more pentagons out of the remaining 25 triangle 1 tiles.

Project step photo 2


Now lay two pentagons next to each other, as shown, and a slot a triangle 2 tile in between them. Tape the tabs to connect the triangle to the pentagons.

Project step photo 2


Repeat step 13 to attach three more pentagons to the two you’ve already connected. Once finished, you will have a single long curving piece. This is the roof section!

Project step photo 2


Stand the whole piece up and pull the ends towards each other to form a circular shape. Leave a gap at the front for the top of the door, so you can easily enter the den.

Project step photo 2


Slot the five remaining triangle 2 tiles into the V-shaped spaces around the dome’s top edge. Line up the tabs and tape them together.

Project step photo 2


Place the remaining pentagon into the gap at the top of your dome. Tape the tabs together to complete the roof of the dome.

Project step photo 2


Now, make the wall of your dome. Start by taping the left-hand tab of one square tile to the right-hand tab of another square tile.

Project step photo 2


Repeat step 18 to link all nine square tiles in a line. Stand the piece up and arrange it into a circle. You have now finished the wall.

Project step photo 2


Now pick up your domed roof and lower it onto the wall. Make sure the tabs on both sections line up where they meet.

Project step photo 2


Tape the wall and roof section securely together with strong tape.

It’s time to paint your dome den! Choose a bright selection of colors.


Add fairy lights to the roof of your den to make a starry ceiling, or turn your den into a space base, tortoise, woodland hideout, or igloo!

1.) Use a sharp pencil to pierce holes through all the triangular roof tiles of your dome.

2.) Take a string of battery-powered fairy lights, and push a light through each of the holes in the roof.

3.) Turn the fairy lights on, and the roof of your dome will be filled with twinkling stars!

Space base

Paint your dome gray, then decorate the roof with futuristic designs. Add a satellite and antenna to your space base.


First, paint the dome brown for the shell. Then make the head and legs and tape them to the tabs.

Woodland hideout

Decorate your dome in a green and brown camouflage pattern. Add twigs and leaves for a woodland look!


Paint the dome in icy blue and white colors. Then stick iceberg-shaped pieces of cardboard to the outside wall.

Out of the Box by Jemma Westing

Twenty-five interactive cardboard model projects that engage kids’ creativity and “out of the box” thinking skills through hands-on learning and the application of science-based principles.

Kids can bring old cardboard to life and build recycled creations they can play with, sit in, and wear.

Supporting STEAM education initiatives and the Maker Movement, Out of the Box includes 25 interactive cardboard model projects to inspire kids’ creativity through engaged and hands-on learning, and, as the founder of Maker Faire Dale Dougherty says, “to realize with their hands what they can imagine in their minds.”

From small-scale gifts to large constructions, author and award-winning paper engineer Jemma Westing uses clear, step-by-step instructions to show kids how to make dinosaurs, masks, race cars, and so much more, and inspirational images encourage them to make their own unique models when they are feeling more confident. The projects utilize only recycled materials, including cardboard rolls and boxes, so all the supplies should be easy to find right at home.

Build something brilliant with Out of the Box. The possibilities are endless!
