Size 138 is commonly used for thicker leather products such as tote bags, sewing leather patches onto caps, straps, belts, luggage and saddle bags. Size 138 is also commonly used for webbing and nylon straps. In terms of appearance, it is more noticeable than size 92 and is a good choice when sewing thicker materials and preferring the stitches to stand out.
