Spiderwire Dyneema Fishing Line
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.
