In weaving, what is the term for threads that lie in a vertical position?

In weaving, the term for threads that lie in a vertical position is "warp." The warp threads are the foundational elements of the fabric and provide the structure and stability required for weaving. They are set up on the loom in a parallel orientation, creating a framework through which the weft threads, which run horizontally, are woven. This interplay of warp and weft threads is essential for creating textile patterns and designs.

The other options refer to different concepts within the weaving process. The weft is the thread that is woven across the warp, while twist pertains to the way fibers or threads are twisted together during spinning or weaving. A bobbin is a tool that holds the thread but does not refer to the threads' orientation in the weaving process. Understanding these definitions is crucial for anyone involved in textile arts, enhancing their knowledge of the basic terminology and techniques used in weaving.
