A gathering gauge for assisting in the fabrication of a gather in a sewn article of manufacture. The gathering gauge is used to evenly distribute a given length of a fabric over a selected gather length, thereby eliminating guess work normally associated with such task. The gathering gauge is an elongated member defining a first slit for receiving and holding one end of a thread used to gather the fabric. A plurality of second slits is provided for receiving and holding a further portion of the thread. The second slits are disposed along the length of the gathering gauge at pre-selected distances from the first slit. A measuring guide is provided for determining the distance between the first slit and each individual second slit. Thus, depending upon the length of the fabric to be gathered, and either the length of the gather or the amount of gather desired, a particular second slit is selected.
