I made a leather ball bag to carry my round balls in. The leather is a Biz tanned deer hide that I tanned. The bag itself is cut from a pattern I made my self; it is in a bit of a heart shape with the top necked in some. The bag is stitched together with a nylon thread then turned it inside out. Then to finish it I punched six holes in it for the leather strap to go through. Pretty simple and fast to make and really looks like something a person a few hundred years ago might have used.
