Singer Sarah Steffen‘s menstrala print (above) uses ink rather than blood to represent that sinking feeling that you experience when you pull down you pants, only to realize that your period has already started. Her work is a contemporary take on a long standing tradition of representing bodily fluids in artwork.
“Coined in the early 2000s by the “menstrual painter” Vanessa Tiegs, the term menstrala describes art created from menstrual blood as a way to rid the shame associated with it. The 1970s saw the emergence of period blood art in association with the women’s liberation movement, with a flurry of artists producing work inspired by that time of the month.”
