I was recently at an art show in Boston and was asked about the fabric-making process. I often use the terms "warp" and "weft" and have received a few questions about what it is and how it works.
Simply put, the warp and weft are the two directions the yarn takes as it becomes fabric. The "warp" is essentially the longitudinal or lengthwise direction of the yarn. It is wound onto the beam and put under tension. The "weft" is inserted and drawn through the warp going over and under the warp threads.
Now imagine the infinite variations for either warp or weft. Welcome to the world of making fabric!
