The difficulties in technique are easily overcome; an important aid in this matter is the use of materials exactly right; this means needles and threads of the correct size, the ground composed of suitable fabrics, and properly strained in a frame. The aim in the working is to get each stitch perfectly flat and straight in its correct place in spite of the obstinacy of the metal thread; to avoid making the perforation larger than necessary, for this makes the work clumsy; to make each succeeding line lie closely beside the last one, for the surface must be of solid gold, and if the ground showed through in places it would impoverish the effect.
The direction of the couched thread is usually either vertical or horizontal, and it may be both of these in the same piece of work. The reason of this may be because it is worked by counting the threads of the fabric, or because the pattern is always treated as a diaper and placed upon the surface without regard to contour. The exception to this rule of direction is when the couching is taken along a stem or the narrow hem of a robe to form the border, or along a girdle, it then follows the direction of the band, this being evidently the most straightforward and satisfactory method to use for the purpose.
