Hand stitch, also known as saddle stitch. In terms of durability, hand stitched products exceed those stitched by machines, since two threads are used. When it comes to the final appearance, hand stitched products are well known for its elegant, steady and uniform lines of stitches with neat and even holes. All of these features of just a tiny line of stitches indeed greatly contribute to the sophistication and aesthetics of the whole product. Meanwhile, machine stitched products are full of crumpled holes with spiky torn threads lacking such beauty.
