What term is used to describe everything needed to complete a sewing project except fabric and patterns?

The term used to describe everything needed to complete a sewing project except fabric and patterns is "notions." Notions encompass a variety of small items that are essential for sewing projects, such as thread, buttons, zippers, pins, safety pins, interfacing, and other similar items. These items play a critical role in the construction and finishing of a sewing project, ensuring that it not only comes together well but also functions as intended.

While supplies could encompass a broader range of materials, including fabric, and tools generally refer to implements like scissors and sewing machines, notions specifically identify the small, often overlooked items that are necessary for completing sewing tasks. Accessories might refer to additional complementary items, but they don't cover the essential components needed for the actual sewing process as precisely as notions do.
