I started out with a 7x7x2" wooden horse I found at a garage sale and sealed it with primer. I loosely drew a design on the horse, but I ended up not following it and worked spontaneously one section at a time. Once I finished the first side, I duplicated the patterns on the other side to match.
Once I was nearly done, I drilled a hole in the backside, created 15-20 beaded strings and then (after grouting the horse) attached the beads for the tail. It took nearly 100 hours to make, but I will definitely be doing this again!
