The Simple Darning Stitch consists of running parallel lines of alternating stitches, short on the back and long on the face of the material. Where these rows come in contact with the lines of the design the thread should be carried over the back and continued in a running line. If the space is wide the darning may be finished in sections on each side, but as far as practicable it is best to carry the silk in continuous lines. The stitches of every row should be taken so as to make the tiny spaces on the face fall exactly in the center of the long stitches of the preceding row. See Figure below. It is very important to have these rows equal in tension and it will require practice to succeed in making them so.
