Welcome to Essenjay Leather Supplies All the leather dog leads and dog collars are cut, sewn and waxed by hand. If you look under Hand Stitching you'll see a few photo's of the various processes, that go into making your dog lead or dog collar. The real benefit of using the age-old method of sewing by means of twin needles is, that should one of the stitches ever break, they don't run. If the same happens to a machine-stitched dog lead or dog collar, then boy do they run! If you don't see what you're looking for on the web site, then get in touch. Nine times out of ten, it can be made. Click here to see more of our dog leads.
