I was in the fabric store the other day and saw glow-in-the-dark thread, and thought it would be a interesting touch to add to a tarp. Wondered if any one has tried this before or if it really works. It was a little pricey, so I didn't get it. Thought it would be cool to do a final hem/seam around tarp, and watch it glow at night.
