If the machine becomes gummed with oil, put a drop of kerosene in each oil hole and at joints and run it rapidly for several minutes. Then wipe off the oil that oozes out with a soft cloth and reoil the machine. It will need a second oiling within a few hours after this treatment.

Stitch the narrow strip to the overlap side (front part of the skirt) and the wide strip to the under lap side of garment (back part of the skirt), right sides facing and seam lines matching. The seam allowance used for attaching the strips should be the same as that of the seam on which the placket is to be fixed (about �). This is to ensure that the stitching line on the strip comes on line with the stitching line of the seam. The one inch extra length of the strips should extend below the placket opening. To finish under lap, crease the strip back over the seam, bring its free edge to the wrong side of garment, turn under � at the free edge and hem the fold to the stitching line. This forms the bound side of the placket and should be � to � wide.
