Untying  Celtic Knotwork
I moisten the girls' backs with water, and sketch the knot onto their skin in Stabilo watercolor pencil first, to make certain it's even.  I ride them to get it perfectly lined up and even with their backbone. Then I henna fast, draping the henna from a carrot bag cut more open than usual.  I brace my right hand against my left to smooth out the line.  I knock out knots in 3 minutes flat. Next!
