French knots, to be successful, must be uniform in size and shape. I have illustrated the most successful method of making them:—
(a) Bring thread up through material.
(b) Hold thread down loosely with thumb.
(c) Place needle under thread.
(d) Turn needle towards you over thread.
(e) Twist needle under.
(f) Put needle into material close to the spot where thread first came through; draw thread tight and hold with thumb; pull needle through to the back of material.
(g) Finished knot.
