What characteristic is primarily associated with the Wilton rug style?

The characteristic primarily associated with the Wilton rug style is the use of a Jacquard loom. This type of loom allows for intricate patterns to be woven directly into the fabric, which is a defining feature of Wilton rugs. The Jacquard loom's capacity for creating complex designs enables the production of carpets with a high level of detail and quality. Wilton rugs are typically made from wool or a wool blend, enhancing their durability and luxurious feel, which complements the detailed patterns made possible by this weaving technique.

In contrast, while hand-woven techniques can be associated with other types of rugs, they are not specifically tied to the Wilton style. Similarly, natural motifs may appear in various types of rugs but are not a defining characteristic of Wilton rugs. The reversibility of the design is more commonly associated with other rug styles, such as kilims, rather than Wilton rugs, which typically feature a single-sided design with a focus on the beautifully woven patterns that emerge from the Jacquard loom process.
