I bought some cheap white cotton sheets from the op shop ($2) and a bottle of red food colouring($1). Then laid the sheets out in the back yard, popped the full bottle of food colouring and some water in a spray bottle, I wanted to acheive a body void on the sheets and as no one in my family would volunteer for this bit I had to it. I laid on the sheets and let Hubby and the kids shoot me and the sheets using the spray creating a lovely/bloody table cloth for later use. I will also be using this for curtains, just rag up the edges. Looks great under black light.
I did find that a tighter woven fabric doesn’t bleed (sorry bad joke) or feather as much
