Anybody use this size thread? I've been having problems finding the right thread tension and get periodic wayward stitches in a continuous run. It seems like it's due to the thread being a thicker size. I'm using a 90/16 needle with 1.9 mm coated fabric (tarp project). I'm about ready to switch to the thinner guterman thread I usually use, but was eating to use this thicker stuff for this bigger heavier tarp. Any other experiences would help.
