The Jacquard machine (French: [ʒakaʁ]) is a device fitted to a power loom that simplifies the process of manufacturing textiles with such complex patterns as brocade, damask and matelassé. It was invented by Joseph Marie Jacquard in 1804, based on earlier inventions by the Frenchmen Basile Bouchon (1725), Jean Baptiste Falcon (1728), and Jacques Vaucanson (1740). The machine was controlled by a "chain of cards"; a number of punched cards laced together into a continuous sequence. Multiple rows of holes were punched on each card, with one complete card corresponding to one row of the design. Several such paper cards, generally white in color, can be seen in the images below. Chains, like Bouchon's earlier use of paper tape, allowed sequences of any length to be constructed, not limited by the size of a card.
Both the Jacquard process and the necessary loom attachment are named after their inventor. This mechanism is probably one of the most important weaving inventions as Jacquard shedding made possible the automatic production of unlimited varieties of pattern weaving. The term "Jacquard" is not specific or limited to any particular loom, but rather refers to the added control mechanism that automates the patterning. The process can also be used for patterned knitwear and machine-knitted textiles, such as jerseys.
This use of replaceable punched cards to control a sequence of operations is considered an important step in the history of computing hardware.

Carpets of Middle-Eastern origin, either from Anatolia, Persia, Armenia, Azerbaijan, the Levant, the Mamluk state of Egypt or Northern Africa, were used as decorative features in Western European paintings from the 14th century onwards. More depictions of Oriental carpets in Renaissance painting survive than actual carpets contemporary with these paintings. Few Middle-Eastern carpets produced before the 17th century remain, though the number of these known has increased in recent decades. Therefore, comparative art-historical research has from its onset in the late 19th century relied on carpets represented in datable European paintings.

Yarn bombing (or yarnbombing) is a type of graffiti or street art that employs colourful displays of knitted or crocheted yarn or fibre rather than paint or chalk. It is also called wool bombing, yarn storming, guerrilla knitting, kniffiti, urban knitting, or graffiti knitting.
