Upon closer inspection, the disks appear to be made of wax paper. I think one could recreate this look by layering two pieces of wax paper with colored tissue in the middle and then applying an iron (but make certain you put something like a sheet between the wax paper and the iron). I think I am going to have to try this out and report back. In the mean time, enjoy the few photos I snapped!
Wouldn't they beautiful in a baby's room? Or strung-up at a party?
