Crimson Wall Tapestries

Tapestry is a form of textile art, woven on a vertical loom. It is composed of two sets of interlaced threads, those running parallel to the length (called the warp) and those parallel to the width (called the weft); the warp threads are set up under tension on a loom, and the weft thread is passed back and forth across part or all of the warps. Tapestry is weft-faced weaving, in which all the warp threads are hidden in the completed work, unlike cloth weaving where both the warp and the weft threads may be visible. In tapestry weaving, weft yarns are typically discontinuous; the artisan interlaces each colored weft back and forth in its own small pattern area. It is a plain weft-faced weave having weft threads of different colours worked over portions of the warp to form the design.

Most weavers use a naturally based warp thread such as linen or cotton. The weft threads are usually wool or cotton, but may include silk, gold, silver, or other alternatives.

Crimson is a strong, bright, deep red color combined with some blue, resulting in a tiny degree of purple. It is originally the color of the dye produced from a scale insect, Kermes vermilio, but the name is now also used for slightly bluish-red colors in general that are between red and rose.
