Frequently Asked Questions
Q. How big are your hides?
A. Our hides average 50 square feet (sf) in area. As a natural product, some may be larger, and some smaller.
Q. How do I know how much to pay if the hides aren't a constant size?
A. Leather is generally ordered by the square foot (sf). Orders should be placed in multiples of 50 sf. Once we process the order and pull the individual hides from stock we invoice you for the exact square footage of leather that you will receive.
Q. Where are your hides from?
A. All of our hides are of Northern European origin, and are tanned and finished in Scotland at either Andrew Muirhead or Bridge of Weir companies. All hides travel less than 300 miles to the tannery, decreasing their carbon footprints.
Q. Can I order less than a full hide?
A. Yes, you may. Half-hide orders are possible if ordering from our Taransay or Sateen leather stocked here in the U.S. There is an additional charge of $0.95 per square foot for these orders. All other leathers must be ordered in increments of full hides.
Q. What is the difference between the leather you have in stock in Bellevue, Washington and the leather you keep in stock at the tannery?
A. Our Taransay and Sateen lines are kept in stock in Bellevue, Washington. The other stock leathers are kept at the tannery’s UK distribution facility.
Q. What is the lead-time on your leather?
A. Subject to availability, hides kept in stock here at DIPI can generally ship out same-day depending on the time you place the order. Please allow 5 -7 working days for other stock leathers.
Q. Can I order leather in custom colors?
A. Yes, you absolutely can. Although we offer an unprecedented range of stock leathers, we always welcome the opportunity to match any color for a custom order. Please call us for details.

Columbia Faux Leather
Q. What is the difference between Columbia 2-Way and Columbia 4-Way stretch faux-leather material?
