SolarLeatherMachines Report post Posted March 3, 2017 I think a previous poster mentioned that the S point allows the hole to close very quickly. That, combined with the black cowboy thread, which is very stiff, is probably causing the issue. If you can try a softer style of thread on the bottom, that might do it....and it wouldn't hurt to use the recommended needle. Quote Share this post Link to post Share on other sites

Biothanes website recommends a round point in either #25 or 26 Stop wasting your time. You are not going to get a good stitch in Biothane with an S point needle! Order a pack each of round point needles (System 7x3) in sizes 25 and 26 and be done with it. Quote Share this post Link to post Share on other sites
