Don't know if this has been asked before, but has anyone tried using Spiderwire line for sewing thread on any DIY projects. Comes in several different strengths (in pounds) and I think the smaller diameters would work as thread for sewing. I can assure you you can't break this stuff with your bare hands, at least not most of us. It is tough and requires a sharp blade to get a clean cut.
I'm thinking this could be used for edging seams, corner reinforcements, or other places that have higher tension forces.
