For a while now, I have been wanting to build a bosal, but the nose button has given me problems. Recently I finally had the time to sit down and study it with the help of Alan's pictures. I started practicing with paracord and a thick cotton rope as the body. After tying it several times, I am comfortable enough to pull out the rawhide. I have continued through the process with the practice bosal with the thoughts of using it for training colts. I took a picture last night after I had started working on the heel knot foundation. I had left the core in the paracord so that is why there appears to be a couple gaps in the nose button.
Thanks again to Alan for taking the time to explain his process of building the bosal.
