1) one sheep kidney
these are most like a human kidney, but are smaller, so i will have to allow for that by making smaller paper, I’m estimating around a5 size paper should make the kidney seem big enough when placed on the paper.
2) fake blood
having a theatre background, i know what i need:
red food colouring
green food colouring
3) brown string and wapping paper.
4) teabags and coffee to make a suitable parchment paper, not aged, but with a brown texture.
5) odd bits of wood and stain to make fake floorboards.
