Mordanting with blood

I’ve been curious about mordanting with blood ever since I read India Flint’s passing reference to it in Second Skin. I’m not a squeamish person and I have ready access to a cruelty-free form of blood each month with my menstrual cycle, so I thought I would give it a go. I wondered if it would give similar results to other protein mordants, or whether the particular properties of blood would effect the results.

To prepare the fabric, I simply soaked it for about an hour in the water I had soaked my cloth pads in. Then I lay it flat to dry and let it set for about a week before eco-printing.

The mordant definitely worked, although the prints were fairly light. Next time I would try to use more blood and soak the fabric for longer to create a stronger mordant. I might also try a series of ‘dipping and drying’ as is done with soy mordants, and see if this gives more vibrant results.
