What is a slub, and how frequently does it occur?

Slub: Fabric woven from yarn or thread containing lumps or thick spots. A slub in a pillow, throw, or shade refers to a type of fabric texture characterized by irregular, slightly thickened spots or lumps in the yarn. These slubs are intentionally created during the spinning process to give the fabric a unique, textured appearance. Slub fabric has a natural, organic look and feel, often associated with a casual, rustic, or handcrafted aesthetic. When used in pillows or throws, slub fabric adds visual interest and a tactile quality, making these items stand out in home decor.
