high-warp loom

A high-warp loom is a type of loom where the warp threads are strung vertically. This is in contrast to a low-warp loom, where the warp threads are horizontal. High-warp looms are often used for tapestry weaving.123

In tapestry weaving, the weft threads are used to build up the design, with each color of weft only covering the area where that color appears in the pattern. The weft threads are pushed tightly together, completely concealing the warp threads. The thickness of the warp influences the thickness of the finished tapestry fabric.2

European tapestry can be woven on either a vertical high-warp loom or a horizontal low-warp loom. While low-warp looms are more common, the high-warp loom has traditionally been used by renowned tapestry factories like the Gobelins.2
