I said I would let you know what we did with our colourful collection. So here it is, above. We made magic!
When I was a little girl, my mother used to make chocolate paper pictures. She first drew - usually a beautiful seated woman or girl - on the glass, then filled in most of the background with black paint. By placing shiny chocolate papers behind the black paint, she made a gorgeous dress for the seated figure. A gold paper would make her hair, and another colour her shoes.
Eventually I was able to make my own, after saving lots of papers. (My mother loved chocolates, which was quite handy).
