I guess that you can tell that I have been knitting lately. The clapotis is coming along nicely, but I am still working on section 2. Anyway, here is a link to a tutorial for making your own "soft" cables/cords for the Boye Interchangable Knitting Needles.
http://www.craftster.org/forum/index.php?topic=360820.0 If you have this set of needles, you know what I am talking about. The needles are wonderful, but the cables are just horrible. I was able to find everything that I needed without having to order anything from Amazon. I found the weed eater line at WalMart, and I found the 2-56 screws at a company called Fastenall. A salesman at an independent hardware store recommended a fastener company for the screws. By the way, they only had the 2-56 screws in 3/4" length, but that was plenty long enough. Also, in the directions it says to cut off the head of the screw and sand the rough edge of the screw so that one does not strip the threading in the needle. If the rough end of the screw is placed into the tubing, there is no need to sand the rough edge of the screw. I now have "soft" cables in sizes 24", 47" and 60", and they are wonderful.
