Now SuperTopo is trying to steal away our dork.

 

If you are using a Sharpie for laboratory glassware marking you might care about trace elements if you were performing ICP-MS analysis. It's so sensitive that when the glassware goes through the wash the marking can transfer from the outside of the glassware to the inside. I'm a chemist but I am just guessing.

 

I wouldn't worry about damaging the rope with your needle, provided that you don't use one of those needles that feature a triangular tip. Those can cut. Use a round needle.

 

Make several passes, laying the thread lengthwise so it's less likely to cut. Leave 3-5 inches sticking out on each end of the thread. When it wears out, replace it.
