I bought a book ages ago from a charity shop and when I got it home a loose page fluttered out with instructions for making an angel mobile from paper. I have adapted the instructions I found- and which appear to have been lost in the move- to use paper plates to make hanging angels. The instructions seem complicated but after the first one it makes perfect sense and they are quick to make, I promise.
So you need to fold your plate in half, with the shiny side on the outside. Then you need to fold one side back on itself- to create a 2cm deep strip through the middle-ish of your plate.
