Care: These vegetable tanned leather cords need minimal care and maintenance. Just like hands, leather can get dry & needs moisturizing. Cocoknits suggest, if needed, treat the cord with a thread conditioner to keep your cords smooth and limber. Screw the needle on only until it is attached to the cord. If you continue to over-screw, you risk breaking the leather inside the needle. Snipping the end of your leather cord at an angle will facilitate attaching the needle. Leather has a grain, so be sure to "go with the grain" when sliding stitches on & off the cord.
