Anne Bonnys Locker Report post Posted January 9, 2014 Outsole stitching is through leather but it is a chain stitch. The Puritan machines can make light work of 3/4" of leather and are a needle and awl chain stitch. Quote Share this post Link to post Share on other sites
neelsaddlery Report post Posted January 19, 2014 Hello: Most leather sewing machines use a lock stitch. This is the stitch of choice for leather because it is the most durable and resistant to tearing. It is an excellent stitch for leather because if these properties. There are always exceptions. As mentioned the Puritan machines used a chainstitch. For saddles, bridles, harness and reins a lock stitch is the best choice for strength and cosmetic appearance. Hope this is useful to you.
