Learn more about leather crafting with this helpful video from Metal Complex. This video will show you how to use a 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 stitches to mimic a machine-sewn look. The tool does not create holes in the leather; it just marks where they should be created.
