Because it is a natural material, and the processing method used by the skinning factory is a vegetable tannin process with less damage to the cortex, there are inevitably a small amount of "scar" and "wrinkle" and "blood gluten" on the leather surface. When we open the material, we will try to avoid it, or put these parts in the parts of the product that are not obvious or unstressed. 2. Handmade stitching We did not use a sewing machine to make our products, all of which were hand-stitched. Before sewing, you need to use a special diamond to punch the suture hole on the leather. Only in this way can you sew a beautiful wavy stitching effect, which is different from the sewing thread of the machine. Although this will greatly increase the production time of leather goods, it is also an important step for the leather craftsman to give the leather soul and warm hand. 3. Hand-polished and polished. Before the finished product is finished, the leather edge is polished and sealed. In order to make the leather look smooth, round and natural. The “tangent pie” has its own set of edge sealing methods. First use sandpaper to sharpen the sharp edge of the leather edge, then apply a layer of edge sealant to make the leather edge look flat. Repeat 2-3 times, then apply a layer of edge-sealing wax, and then polish it with a polished rod until it is polished. The leather edge looks smooth. 4. Hand dyed leather The “tangent” hand-dyed products currently use Fiebing's leather alcohol dyes imported from the United States. In order to dye evenly and naturally, we need to wet the leather with water, and then apply the dye over and over again with a sponge, from light to deep, until we reach the color we want. After drying, a layer of fixing agent is added to increase the color fastness. Also use water to apply on the surface of the skin, wipe off the dust on the surface and make the color more uniform. Because it is hand-dyed, there are subtle products between the colors of each bag, each of which is different.
