Dobby is a type of decorative weave produced by a special attachment on a loom. The characteristic dobby patterns are small, geometric, straight-edged and regular in their repeat.
Dobby is also the name of the attachment which allows additional yarns to be woven into a fabric by controlling the action of a number of harnesses, creating dobby weave fabric. Dobby may also refer to a loom with the dobby attachment.
Compare dobby to jacquard weave, which is characterized by large-scale and curving patterns.
