Which type of trimming is NOT typically sold by the yard?

Accessories are not typically sold by the yard because they often come as individual items or in sets that are ready to use. Accessories in the context of textiles for interiors can include various embellishments such as buttons, tassels, and decorative hardware, which are packaged for convenience and typically used on specific projects, rather than being cut and sold in longer lengths like trim.

In contrast, cords and gimps are types of trimming that are often sold by the yard because they are used to finish edges or embellish seams and are usually purchased in longer lengths to accommodate larger projects. Banding is also sold by the yard as it is often used to provide a finished edge or decorative touch on a variety of items. Thus, accessories stand apart from these other trimming options by their nature of being individual items rather than lengths of material.
