Lots of denim enthusiasts prefer a chain stitch finish on their hems because it creates an effect which is commonly called 'roping'. The stitch that is made on a chain stitch machine has a specific loop and tension which makes the rolled denim warp and 'rope'. When the hem ropes it fades in what would be considered a classic jeans hem look. A lot of companies use modern chain stitch machines but we have found they can't get the results that we can from our collection of vintage machines. Our tool of choice is the Union Special 43200G. Originally used for decades by the pioneers of denim, Levi Strauss, this machine is now out of production, but we've built up quite a collection and so will be providing authentic chain stitch services for years to come.
