Farmed Buffalo hide tanned to Light Brown colour. This brown is a light milk chocolate tone (think: Quick chocolate milk lol). Very soft and supple and easily sewn by hand. The 3 1/2 will make amazing moccasins, mukluks, bags, vests and jackets, while the 5 1/2 is heavier Moccs/Mukluks or for bags.. These are halve buffalo pieces and are quite huge running from 19 sq ft to 25.
