What is thrumming?

Thrumming refers to a textile technique that involves adding extra warp or weft threads into a fabric in a decorative manner. These threads are typically looped over the surface of the fabric, creating a tufted or fuzzy texture.

Thrumming is commonly used in traditional textiles, such as Scottish tartans and Scandinavian sweaters, as well as in contemporary fashion and home decor. It can be done using various materials, including wool, cotton, and silk.

To create thrumming, the extra threads are inserted into the fabric during the weaving process or added afterward using a needle or crochet hook. This creates a raised, dimensional effect on the surface of the fabric, adding texture and visual interest.

Thrumming can also be used to add warmth and insulation to garments, as the looped threads trap air and can help to keep the wearer warm. However, it can also be delicate and prone to snagging, so care must be taken when wearing and washing thrummed fabrics.
