This series of pictures shows how to make a 3D Blitz Picture of the London skyline. Please feel free to change the materials or setting in any way. I wanted to show you with what I could find- I bought nothing specifically for this. In the end I used plant pots for some of the buildings in the foreground just to add the feeling of depth to it. The flames were made from an old red napkin and the searchlights were made from scrap A4 paper. The whole thing is backed onto the side of an old cardboard Amazon box. The only painting we did was a tiny bit of black paint for the planes and we cut a paper plate in half and painted it black.
Good Luck! It took Alice and I a couple of hours including waiting for the glue and paint to dry.
