The latest creation of the Proper Leather Studio is a Celtic knot leather cuff in black and yellow with intricate details. The cuff bracelet is made of high quality veg-tanned leather (1.6-2.0 mm (4 to 5 oz) single bend European hide.). It is entirely handmade, from pattern transfer to incision, tooling, dying, and finishing. The background was dyed by sponge and the pattern with a small brush. As for the finish, the bracelet is protected with several layers of acrylic finish (sheene and resolene) and the edges and back are polished and waxed. The closing system of choice is with leather lace as it allows for a good fitting on almost all wrist sizes and is not uncomfortable to wear as metal snaps usually are.
