Conductive Thread Woes

     I was testing out the conductive thread we have available to use and I found what may be a problem: the resistance per length of thread is so high that when a power source is connected a small distance away from the LED, it does not light up!  Upon further investigation, I found that when the probes of an ohmmeter are placed approximately one cm apart, the resistance is between .5 and 1 ohm - an acceptable amount.  However, when the probes are placed approximately 10 cm apart, the resistance jumps to between 5 and 10 ohms - too high for reliable usage. 
     One solution to consider is braiding multiple strands of wire together in an attempt to lower the resistance per length of thread.  Another possible solution is switching to another material - maybe even metal wire - to build the prototype.  This solution would allow light measurements to take take place in order to see if the project is worth pursuing in the future.
