Which construction can have cut and loop pile but cannot have intricate designs?

Velvet is a type of fabric characterized by its smooth, soft texture, typically made with a cut pile. While velvet can be produced in various textures and patterns, traditional velvet construction does not involve intricate designs in the same way as others, such as Jacquard woven fabrics or specific tufted fabrics. This limitation stems from its manufacturing process, which focuses on creating a uniform and plush surface without complex, varied patterns.

In contrast, Axminster and Wilton are methods of weaving that allow for intricate designs and patterns due to their capability to control multiple yarn colors and arrangements. Tufting, although it involves cut and loop pile, can also accommodate intricate designs, since it is primarily defined by the technique used to insert the yarns into a backing material which allows for detailing. Hence, velvet's construction inherently limits it to simpler designs compared to these other techniques.
