Well, why let cats have all the fun? Colombian artist Zaira Pulido creates her embroidery art using long strands of human hair:
Bogota-based Zaira Pulido has been asking every one of her friends and people she’s into for strands of their hair to use in a series of embroidered artworks. She uses the human hair instead of the usual thread and creates various works, like embroidered portraits of her friends (each made with their own hair), an embroidered comb or a replica of her bra.
