My Mum was fascinated with things made of horsehair. She was intrigued & studied the hand-woven horsehair veil found through Central Asia. You don't see it much anymore, it was from older times. I think it was called the Paranja.
Oh, the versatility of horsehair! Traditionally used in upholstery, lining in clothing, woven for Paranjas, fly swats in Africa, plaited for jewellery, used in headdresses from exotic steppe nomads, paintbrushes & even fishing line. My Mum kept lengths of braid, horsetail & various other things under a glass dome at home & she has embedded me with the same attraction. I am not often without the braided bracelets of horsehair (creams & caramels for me) that I bought in Wyoming whilst horse riding in the Honeycomb Badlands- the stomping grounds of infamous American outlaws like Butch Cassidy & the Sundance Kid.
