I came up with a method of weaving crosses with a string last year. The problem with that method is it only worked in one direction. I came up with another method that works in both directions. http://www.youtube.com/watch?v=FQ9T8fWs7Ws&feature=youtu.be I must admit I am still able to push my crosses a little faster than this tool allows me to weave but I think my speed with the tool with improve with a little practice. If you are new to stringing this may just be the tool to improve your time required to weave those crosses. EDIT for pertinent info in post: The beads I use are Pony Beads aka Kandi, or Candi beads. They can be found at any craft store, Walmart, some drug stores, the bay, dollar tree, etc ... They're everywhere and cheap. This method is not for everyone I can actually push weave faster in the center of the racket. It works very well when stringing full bed poly or gut as it gives you a little extra grip on the string and does not bend up the string. I like it most when I get down near the bottom of the racket and it gets a little harder to weave.
