First print out the template with the little monsters on white paper. Then you can choose your favourite colours from the set and paint the monsters with the thick fibre-tip pens according to your mood. Now you can cut out the coloured monsters.For the next steps it is best to call adults for help:Attach a monster to the thread with the sewing needle and thread two to three pompoms on at a little distance. The mobile looks especially funny if you attach the monsters at different heights. Finally, all you need to do is knot all the mobile parts to the eyelets on the rod.
Have fun with the monster window decoration!
