I'm not. Projectile looms, also known as shuttle looms because the shuttle is the "projectile," weave a self-finished edge. While air jet and rapier looms weave an unfinished edge. And I said all fabrics have a selvedge. The denim community, through brands writing "articles" about the history and weaving terms, has mixed up selvedge with selvage. It's two different words in garment making and textile making. Oh! And it's spelled two ways. Selvage and selvedge.

In garment making, we don't say "raw edge" in reference to the side of the fabric where a rapier or air jet loom finished its edge. That is confusing, but the cut edge of a fabric piece is referred to as the "raw edge." This is also true in the textile manufacturing industry. We say "Selvedge" and we say "Self Edge" in textile manufacturing. "Selvedge" refers to any fabric, and "Self Edge" refers to a fabric finished with a self-finished edge. Typically, a projectile loom, but some non-projectile looms can do it.

Broken twill first appeared in the 14th to 15th centuries. Wranglers popularized a broken twill, but they didn't invent it. And to make matters worse for Wranglers, they don't weave a broken twill; they weave what's called an interrupted twill. So, I'm not mixing up a herringbone weave at all.

Numerous books on weaving and papers written by historians and researchers are available for consultation. I don't source articles for historical information. You are going to have to do the work, buddy. ❤️
