A chambray is a plain weave fabric woven with a colored yarn in the warp and a white yarn in the weft. Like chambray, denim is made with a colored yarn in the warp and white in the weft, but is woven in a twill construction. The chambray’s warp and weft threads will alternate one over the other, while denim’s warp thread will go over two threads in the weft before going under one. Typically, you will notice a lighter color to the underside of a denim fabric, whereas the underside of chambray will appear much more similar to its face side.
