(pronounced SLUHB)

Though it sounds like a name that kids would cruelly taunt one another with, a slub is an important term in the textile trade. When wool is drafted unevenly as it is spun it forms lumps, or slubs, in the yarn, which are thicker than the rest of the yarn and have little to no twist. Once considered a mistake, these irregularities have become a popular effect designed intentionally into various fiber types as they can be used to add beautiful visual and tactile texture to the resulting woven fabric.
