arich Report post Posted October 3, 2016 Just brought home my first industrial! It's a Consew 255 and I'll be sewing about 1/4" (sometimes a little more) tooling leather the manual says up to #8 left twist thread however I don't see either of these when I search for thread to purchase. What is the best to use? I like the look of thicker thread Also- do I need triangle point needles for sewing leather? Quote Share this post Link to post Share on other sites
