Cone Holder

I am starting on a "Warp Rep" weaving project, and need a large number of warp threads. While at Vavstuga last October I saw cone holders used when weaving multiple threads in a warp. I decided that I would like to try using one of these devices at home, but didn't want to spend the $$.¢¢ to buy one.
The result of my attempt to build my own cone holder is shown in this video.
