Top Grain Top-Grain (Corrected Leather) is fuzzy on one side and smooth on the other. The smooth side is the side where the hair and natural grain used to be. Top grain leather has often been sanded to remove scars and then sprayed or pasted to “cover up” the work.

Thickness or Weight – Leather is usually measured in terms of ounces. One ounce equals 1/64th of an inch thickness. Thus, a weight of 7 to 8 oz. means the leather is 7/64th to 8/64th of an inch thickness. In an effort to make leather a uniform thickness, wet hides are run through a splitting machine. However, each animal is different and there is always a slight thickness variation throughout the hide. This is why leathers are usually shown with a range of thickness, such as, 4 to 5 oz., 6 to 7 oz., etc.

Poly Twill Liner
	Poly Twill Fabrics are often used for sturdy work clothing or durable upholstery because of its strength and durability. Twill also recover from wrinkles better than plain-weave fabrics do. When there are fewer interlacing, yarns can be packed closer together to produce high-count fabrics. In twill and higher counts, the fabric is more durable and air- and water-resistant.
