The next difficulty for beginners of leather crafts, installation of fasteners in R part.
This time, it is circular, but I made a jig for mounting fasteners by using the surplus leather.
We will introduce the production video using the jig in the next video.

My late reply. sorry. This is the tool used in the video. amzn.to/3Ez2xtk A replacement blade is required. But I couldn't find the site where the blades are sold.
