As soon as the class meets, the pupils should prepare a 5-inch gauge, to
guide them in turning the hems of the skirts of their aprons. They
should make a half-inch notch in the measure for the first turn in the
material. A half-inch edge should be turned up from the bottom of the
skirt, then a 5-inch hem should be turned, pinned, and basted carefully
with uneven basting. The gauge should be used for both measurements.
