I had also bought some small ones for my children, but we had not unpacked them yet.
The large ones (this white ball, a green ‘pear’ and an orange ‘strawberry’ shaped decoration thing) have been hanging around our room all year long. And then the Christmas tree arrived and I found some gold spray paint in our garage…
We made this Visionär-Jupiter-like constellation by simply spraying the balls with gold spray paint, bought in a DIY store.
The small ones are attached to the larger one with some small golden decoration ribbon (usually also available at Ikea by the way).
