Keystone Sewing Company has made available a handy guide that auto trimmers can use to determine the correct needle point needed to achieve a particular stitch or seam appearance. The guide, originally published by Groz-Beckert, is a must read for all auto upholstery professionals.
This needle guide discusses such important topics as selecting the correct needle point, stitch appearance, seam strength and the influence of leather on seam appearance. It’s only seven pages, but manages to pack a lot of helpful information, as well as photos and diagrams to explain the correct use of needle points.

June 6, 2012 at 7:19 pmI was wondering how come my stiches were slanted. I asked an experience local trimmer and he said….thats normal. Now I see that with a different needle i can do straight stiches. great article!!
