I believe this skin is an "inner skin" that holds in body organs. The needle pierces the top of the piece and is suspended by two strands of hair, as hanger. I made this piece for a fundraiser for Border Crossings Magazine.
This is the second one, the first was unfortunately lost in transit...but it's out there in the world somewhere.
