Postscript: Gina pointed out to me that I failed to mention the most important aspect of her creation. She made it using old Nespresso pods which she flattened to create the disks that the glass stones (not beads) are affixed to.
One of my wife‘s DIY projects was to take some old, coloured
beads glass stones and create these light catchers. I finally got around to hanging it up over our balcony. They’re very pretty when they catch the light.
