Once I had done this, I tore up some pieces of tin foil and added them to the compost.
This I did because it looked like the foil that the Oxo cubes are wrapped in, inside the box of an original pack of Oxo cubes.
I then photographed the piece on a white board, which turned out great. It looked realistic on a larger scale, but most importantly I managed to salvage the work, instead of just moving on to something else entirely.
