Make sure your leather designs are precise and professional with the Metal Complex leather embossing and spacing set. This tool was designed to make even marks on leather for guiding stitching work. Simply insert the wheel that you desire for the spacing of your stitches and then run it along the groove in your leather. It can also be used to press down the stitches to mimic a machine-sewn look. Please note that this tool does not create holes in the leather, just marks where they should be created. This tool comes with two extra wheels.
