I’ll be honest, I am not 100% about the black background. It might look better on some velvet fabric. Perhaps one day, when I’ve nothing better to do, I might look for some suitable fabric and change it. I am not sure how much of the main body of the piece would fall apart, it should be pretty tough as I used E900 clue, but it wouldn’t be too hard to put together again, and maybe add some more bits.
The Ribba shadow box frame came from Ikea, it measures 23 x 23cm and cost £3.50.
