As of today I have ordered some 70d coated ripstop fabric from DIY gear Supply to tackle my first tarp. I have done my homework and figured out what size and stitches etc. i'll be using, however, I haven't come across anything in particular regarding what type of thread to use? Does it matter? I always use Guttermanns 100% polyester ( the heavy coat stuff), but I want to be sure I have all my ducks in a row. So if anyone has any suggestions please share. Thanks in advance!
