The material on which gold embroidery is to be worked should be herring-boned very evenly and firmly on to a backing of linen (never cotton), and stretched in an embroidery frame. Sometimes the gold embroidery is worked on a strong linen, cut out and applied in the same way you do applique. For stitches, see Plates No. 68, 69, 70 and 71. Great care is required to prevent gold and silver threads from turning a bad colour. When applying these metals do not handle the threads more than can be helped. Cover the work as far as possible with unbleached backing as each piece is completed, and take every precaution to protect it from damp. Much of the gold and silver work is lacquered directly it is finished. Silico varnish painted on thinly preserves the colour of the metal.
