These are really simple to make and kids of all ages can help. Mr8 actually showed me how to make one, then we extended on the concept to create this hanging ornament.
It is really just 2 card board stars slotted into each other at right angles to create a ‘3D star’ as he calls them. But we made 4 different sized and hung them form some cotton. We covered each star with some paper from a themed wrapping pack, so they were not all exactly the same, but similar enough to ‘match’. The whole project took about 20 minutes for 3 of us and looks pretty cool! Further instructions available if you open or scroll over each picture.
