Unlike wallets made from other materials, leather wallets are strong enough to withstand the effects of daily use or rough treatment for a considerable amount of time. You can purchase ready-made leather wallets from a large number of retailers, but the cost is usually prohibitive. Fortunately, you can also make your own leather wallet with affordable supplies and equipment. With practice, you can get more creative and produce wallets that appear to have a professional design.
Lay the leather down on a flat surface with the wrong side facing up. Use a pencil and ruler to draw two rectangles measuring 7 inches by 4 inches and a smaller rectangle measuring 4 inches by 3 inches. Cut these shapes out with an X-ACTO knife.
Apply cement glue to one short edge and two long edges of the smaller rectangle. The glue should be on the wrong side. Place the small piece, glued side down, on one corner of one of the big rectangles. It should be about 1/2 inch away from the corner edges of the long piece.
Wait for the glue to dry. Use the awl to make holes along the three glued edges of the small piece and the underlying long piece. Space the holes about 1/4 inch apart. Thread a needle, and pass it through the holes to sew the small piece to the long piece.
Place the two long pieces of leather together, wrong sides facing. Make holes along the three edges of both pieces with the awl. Sew both pieces together with the thread and needle.
Apply a small amount of olive oil to a cotton cloth, and rub the surfaces of the wallet. The oil will condition the leather to prevent it from cracking.
