Top 10 DIY: Montessori Inspired Baby Mobiles Series: Octahedron Mobile

In previous posts, I shared with you the benefits of the Montessori Inspired Baby Mobiles and created a series beginning with the Munari Mobile and following this series I will introduce you to the Octahedron Mobile.

According to this wonderful post at Little Red Farm, it is recommended to introduce this mobile around the first 5-8 weeks of the baby or when she loses interest in the Munari mobile. By this time, your baby starts recognizing colours and the shades that metallic paper creates when rotating.

An octahedron (plural: octahedra) is a polyhedron with eight faces. A regular octahedron is a Platonic solid composed of eight equilateral triangles, four of which meet at each vertex. In this case, we will use 3 different metallic papers to create 3 different octahedrons and present the baby volume and colours: blue, yellow and red—the primary colours.

This mobile is very easy to make and even my husband, Filipe, participated by cutting and drawing the octahedrons on the metallic paper. Obrigada amor!

Here’s how to create this mobile along with the materials needed. Just a heads-up: It will take around 2 hours of your time once you have all the materials together.



– Print this Octhahedron Mobile Pattern

– 3 metallic papers: blue, yellow and red

– 1 wooden dowel or a wire coat hanger

– Ruler

– Scissors

– Nylon

– Pencil

– Cutter

– Glue (I used contact glue) or double-sided tape

* I found all I needed at Staples in Porto.


  1. Print the printable, cut it and use it as a model for the 3 metallic papers.

    1.-Print the printable, cut it and use it as a model for the 3 papers.

2.Cut out the shapes and score along the fold lines. It is important to score these sides well to get a crisp finish to the shape, so I used a ruler and the back of a craft knife.

3.Before assembling the octahedrons, place a nylon thread on the inside of one of the triangles with tape as shown in the picture below.

5.Assemble the shapes using the glue or the double-sided tape. Remember to leave the nylon thread outside the shape so you can tie it to the dowel or coat hanger.

6.Place the shapes at different heights and tie them to the dowel.

7.- DONE! Your Octahedron Mobile is ready!

Your baby will love this “work” and the different shades produced by the metallic finish. Give it a try and let me know how did it go with your baby! I am sure you will enjoy doing it as much as we did.

In the next DIY Montessori Inspired Mobiles Series, I will introduce ypthe Gobbi Mobile.

Stay tuned!
