Some of you might know Dacian as the faceless boyfriend and outfit photographer behind this blog, but today he’s taking a new form. He’s materializing as a hand model and mastermind for this DIY concrete egg tray. I’ve had two attempts at making this object myself before he took matters into his own hands. Finally, it looks perfect. I love the hexagon shape and the way that this is not just an Easter craft – in fact, you can use this all year round, and swap the eggs for round fruit or small decorations.

What you need:

  • 2.5 kg cement
  • balsa wood board, 4 mm thick
  • ruler
  • craft paper
  • pencil
  • sharpie
  • cutter & cutting mat
  • 6 polystyrene balls (approximate diameter of an egg)
  • vaseline & paintbrush
  • tape
  • double side tape
  • small screws and screwdriver (optional)
  • trowel
  • container for mixing concrete (e.g. bucket)

Cutting balls Cutting balls

1. Start by cutting the polystyrene balls. You can choose to cut them perfectly in half, or vary the sizes like we did, to create a more organic shape. 

Measuring Measuring

2. Draw a hexagon on a piece of craft paper. This one is 26 cm diameter, which is designed specifically for 12 eggs. Then arrange the polystyrene balls inside the hexagon. Feel free to move them around until you find the perfect design.

3. Draw the contour of your balls on the paper. Assign ascending numbers to the balls, so you remember how to arrange them later, and repeat the numbers on the circles. This is important if you chose to cut the balls at different sizes. 

Cutting the hexagon

4. Use the cutter and ruler to cut out the paper hexagon, Make sure you do this on a cutting mat!  

Cutting the sides

5. Now let’s start making the mold. Measure and cut six pieces of wood measuring 13 x 4.4 cm (13 is the side and 4.4 is the height of the mold).

Making the mold

6. Then measure and cut the base of the mold, measured against the paper hexagon. Tape the base together and cut off excess tape.

Taping the sides

7. Tape the sides of the hexagon with the tape facing the exterior. Use as much tape as you need to keep the mold very firm. We used an extra layer of duct tape. 

Imprinting the circles

8. Place the paper hexagon inside the mold and trace the circles with a pencil, pressing firmly. This will imprint the right arrangement on the balsa wood. 

Sticking the ballsSticking the balls

9. Stick the balls in their right places with double-sided tape. Don’t use glue, because it will instantly melt the polystyrene! For extra security, we put small screws through the back of the mold and into each ball. You don’t want those moving around! 


10. Cover the interior of the mold in vaseline. Do this with a paintbrush, to make sure you cover every ball and every spot in between. This step will make it easier to remove the concrete from the mold.  

Pouring concrete

11. Mix the concrete according to the instructions on the package. We used 2.5 kg cement to 250 ml water. Make sure you mix it well with the trowel! Pour into the shape and level nicely. If any air bubbles form, carefully shake the mold a little. 

Place the mold on a straight surface, in a place out of the reach of kids, pets etc. Allow the concrete to set for circa 36-48 hours. This will depend on the cement you are using, but it’s better to leave it more than risk chipping at the corners. 

When the concrete is dry, you can carefully remove it from the mold. Start by cutting the tape and removing the sides one by one. Then turn the form upside down and remove the bottom. Finally, remove any balls that didn’t come out with the wood. You can add felt pads to the bottom for protection, and your concrete hexagon egg tray is finished!
