Known for the regularity and distinctness of its tapestries, the royal French tapestry factory in Paris known as the Gobelins used 15 to 18 threads per inch (6 to 7 per centimetre) in the 17th century and 18 to 20 (7 to 8) in the 18th century.
Another royal factory of the French monarchy at Beauvais had as many as 25 or even 40 threads per inch (10 to 16 per centimetre) in the 19th century.
Most of the Chinese and Japanese tapestries have both warp and weft threads of silk.
Pure silk tapestries were also made in the Middle Ages by the Byzantines and in parts of the Middle East.
In the West, tapestry traditionally has been a collective art combining the talents of the painter, or designer, with those of the weaver.
Until the 19th century, tapestries were often ordered in Europe by the “room” rather than by the single panel.These excessively fine grains make the fabric very flat and regular, tending to imitate the canvas of a painting.The grain of 20th-century tapestry approximated that used in 14th- and 15th-century tapestry.A tapestry set is a group of individual panels related by subject, style, and workmanship and intended to be hung together.The number of pieces in a set varies according to the dimensions of the walls to be covered.The warps in a finished tapestry appear only as more or less marked parallel ridges in the texture, or grain of the fabric, according to their coarseness or fineness.The thickness of the warp influences the thickness of the tapestry fabric.Though he followed the painter’s directions and pattern fairly closely, the weaver did not hesitate to make departures from them and assert his own skills and artistic personality.In the Renaissance, tapestries increasingly became woven reproductions of paintings, and the weaver was no longer regarded as the painter’s collaborator but became his imitator.The advantages of wool in the weaving of tapestries have been its availability, workability, durability, and the fact that it can be easily dyed to obtain a wide range of colours.Wool has often been used in combination with linen, silk, or cotton threads for the weft.
