This issue teaches you the edge sealing method of vegetable tanned leather. If you want to get a beautiful edge seal, the leather needs to have good density and oil. If the leather you buy is not that good, you will need to put in more effort to make it. I’ve seen it in the past, so I suggest you try to buy better leather when buying leather in the future, so that the things you make will become more beautiful when stepped on
