A 4/5 ounce piece of pull-up leather that has been made into a large bucket bag.
The bag measures 16x13x6 with a 10 inch base. The gusset is hand stitched using the saddle stich method and I used a thick nylon thread than I ran through some beeswax. The side is stitched up with 1/4 inch strips of leather and ran through 14 eyelets on each side.
The strap is 1 inch wide and can be adjusted using the buckle, for the length that is comfortable for you.
The inside is HUGE and comes unlined.
