Pro Tips:
1 - rotate anti-clockwise to untwist and lay perfectly flat. With just 2 or 3 light wraps of Nano Silk over foam you can then tighten and tie in foams or materials that would cut easily.
2, use white Nano Silk and simply color the last 4 inches (100mm) of thread for heads in a visible color.
