This is exactly the kind of thing I love. It makes something out of nothing. But it's not my idea. It comes from Jane Crosland on the Facebook page Dollhouse miniatures made from everyday things.
Using very sharp scissors cut out the gold plates that are hiding in the bottom of each section.
This is why I end up saving bottle caps and all sorts of little interesting pieces of plastic.
I also found another use for candy box inserts. This this idea makes little pots and pans. http://dollhouseescapes.blogspot.co.uk/2015/01/kitchenware.html
