Dan Riley (www.scisci.org) made a beautiful Fabric Ribbon cable. 8 separate lines of are woven into the fabric. The end of the cable is connected to normal 16 pin plug as normal ribbon cable. Since you can not place the conductive threads very close, only 8 of the pins are used on the plug. The is made by professional weaving machines, but perhaps it is also interesting to try this method with hand weaving.
