I am looking to start making some of my own gear but have a couple questions. I have read that the thread sold by thru-hiker, tex 30 and 40, is appropriate for myog projects. I have a sewing machine sold by sailrite designed for sailmaking and sail repair. Sailrite sells the thread below as appropriate thread for <1.5 oz/sq yard projects. Is there any reason why i should not use that thread for any of my outdoor gear?
