For close-studding the edges of upholstered chairs, procure a gauge to the shape of the accompanying sketch. For ordinary fin. brass studs the points of the gauge should be Jin. apart. In marking for studs, put the last point of the gauge in the last hole made before striking again, to ensure that the holes shall be at equal distances apart. To save burring the stud heads, drive in with a raw hide mallet.
