Thread the needle with a length of thread approximately 24 inches (~61 cm) and tie a knot at one end of the thread. For more details see Needles and Thread.

From the backside, insert the needle through to the front at a marked stitch line. Overlap any existing stitching by at least 1/2 inch (~13 mm).

Pull the thread through until the knot lies flush against the back of the fabric.
