I decided since I had leather and I do leatherwork that I would go ahead and wrap my Billet box after having sealed the pin etc etc... So here is.. the good, I like the color of the leather and thread combo. The sleeve fits fine and is removable without a pry bar. The bad... The leather is oil tanned so it's a little stretchy. I'm hard headed so I didn't make a pattern. (Really bad I know better). My bottom stitch line looks like garbage, I need to use my stitching awl more often. I have been spoiled to my stitching irons.... The ugly.. the holes look like a 5 year old made them cause the stretch and lack of a pattern.. Anyway it's mine, I like it, and it'll keep my Billet box from getting scratched if I drop it or I should say when I drop it!
