I would definately second the video. I bought a video too, which showed how to make the jig and the strings, but was considering just buying the jig first. The nice guy at 3 Rivers talked me into the video years back.
Glad he did. The jig was easy as pie to make. The strings were another story. No way I could have bought the jig and then read the instructions on the making of the actual string. Even with the video and seeing it done before me, I screwed up MANY strings. Learning to make bows was less frustrating to me than strings.
