Do not forget that, after one side is overcast, it is necessary to turn the buttonhole around so the other cut edge may be overcast.

Making the buttonhole stitch. When the buttonhole has been overcast, the needle should be in position at the beginning of the buttonhole where the overcasting was started. Point the needle at right angles to the edge, and take a stitch one-eighth of an inch deep (Fig. 30). Hold buttonhole so that it lies flat on top of the first finger. Do not spread it open. Throw the double thread from the eye of the needle, around the point, in the same direction as the buttonhole is being worked, from right to left. Draw needle through, pulling the thread at right angles to and toward the cut edge of the buttonhole. A little finishing loop called the purl will be formed at the edge. It is this which prevents the edge of the buttonhole from wearing. Continue along one edge until the corner is reached. Remember all stitches are to be the same depth and to have about the space of a thread between stitches, and the purl is to lie exactly on the edge.

Turning the corner. There are several ways of finishing the corners of buttonholes. They may have two fan ends, or one fan and one bar, or two barred ends. How can we tell which way to plan? A barred end is stronger than one which has only a fan. One must judge how the buttonhole is to be used, and then make the proper combination of ends. The picture (Fig. 31) shows both the fan and the bar. The fan is made with the same buttonhole stitch. Five stitches make a good fan. The third one is taken on a line with the cut and is the deepest, and the two stitches each side are slanting and of a depth to make an even fan effect at the turn. The fan can be made more easily by turning the buttonhole so that the end to be worked with the fan is pointed towards the worker and the cut edge is over the finger.
