Here is a sensor test that I conducted. I sewed paths of conductive thread down muslin. The conductive thread is only on one side of the muslin. I used a multimeter to test how conductive the thread is. Perfect conductivity, like that of a steel wire, is at 0.0 resistance.

Below: Here is a test of conductive thread of wide-stitched thread. The result is 3.3 ohms resistance.

Below: Here is a test of conductive thread of tight-stitched thread. The result is 3.3 ohms resistance.

Below: Here is a test of conductive thread of medium-stitched thread. The resistance is 2.8 ohms.

Below: Here is a test of conductive thread that was run backwards and forwards multiple times. The resistance is 0.4 ohms.

Below: Here is a test of conductive thread that was run backwards and forwards multiple times at the ends to allow for alligator clamping. The resistance is 2.8 ohms.
