See 'Cow Leather' for details. One thing to note is that we tend to sell these hides in a thicker weight (slightly thinner upholstery weight). Also, some are sold in smaller pieces than sides, so they will measure less than 20 square feet. It depends on the item - just ask for sizing on a particular color. See the 'Guidance' section for more information. To place an order, please call (212) 302.2332.
