'Original Jean' Narrow Fabric Cutting Plan

This Original Jean Design and Leg Shape originated during the West Coast Gold Rush of the USA when Utility Workwear Jeans were made from the Sailcloth and Covers from the Sailing Ships and Covered wagons which carried the Miners from overseas.

The Original Looms which took over the production of Denim Fabric were only 36in wide.

I am sure that the inside seams would have been cut as a single straight line in those days.
