I just made my own 3 under tab this week from some spare leather I had lying around. It's not cordovan but works real well. There at several videos out there on how to make one or do an image search to help get started. I'm no leather worker but the one tip I'll give is to sand the edges of the tab to give a smooth, comfortable edge. Start larger and trim a little at a time until you get the custom shape that works for you. Then you can cut aa many as you like and have extras everywhere!
