The term 'spinning wheel attachment' refers to two components of a spinning wheel, the DISTAFF and the TREADLE. The DISTAFF is a staff or pole used to hold fibers such as wool or flax while they are being spun into thread. The TREADLE is a foot pedal used to rotate the wheel, allowing the spinner to control the speed and tension of the yarn. Together, these two components form an essential part of the spinning wheel, allowing the spinner to create yarn from fibers.
