Rugged, attractive and low-maintenance. Not just attributes for the perfect partner, I exclusively use this thread for all my leather hand-stitching.
At 1mm thick, this waxed thread is very strong - it has never failed in any of my projects, where I've successfully tested stitched-in hardware with my bodyweight. The flattened braid has a lower profile than round thread, so is less likely to get caught and abraded.
The thickness is enough to highlight your stitching as a design feature without it becoming overbearing. My personal favourite, the cream colour, is slightly off-white, which complements or contrasts well with just about any leather without projecting the overly artificial feel that can come with pure white. I'm also offering the thread in black for a bit more contrast from a light natural leather, or a subtle look with dark leather.
Because the thread is pre-waxed, it will lock into place well against the leather without the additional fuss or mess of waxing your thread. Having said that, it will still take on more wax easily if you want a little additional security.
