There is a women here who has written a book on this. Can't remember her name now but I know her book is in our library and I'll look into it and report back. JoAnn
http://www.outside-art.com/HorsehairArt.html I was curious so I googled it too. Seems they add horse hair into thier creations here is just one place I found. I had heard of it in the ropes before kinda cool.
I have the first book on Hitched Horsehair, just wondering if anyone out there did it. I can't travel to Idaho, unfortunatly. But I would like a hands-on learning experience.
