Warp yarns are wrapped around the finished roll, and the cloth is actually made from the weft.

Weft yarns go across the warp, from "weft to right".

Explanation

Weft yarns go across the warp, from "weft to right".

10. Traditional glue-based gesso is a hard painting ground that can be used on stretched canvas.
