Suppose it is desired to put a weft back to the pattern, [Fig. 320], and to have two face picks to one back pick. The face pattern must be put on the face picks as in [Fig. 321], and the back pattern must then be put on in such a manner that where the backing weft is passing over one of the warp threads there must be at least one weft dot above and below it, as in [Fig. 321].
Two wefts of different colours may be made to form reversible figures by making them change places, first one being on the face, and then the other. The principle is shown at [Fig. 322], where the alternate picks are of different colours. The two wefts should be thick enough to cover well, and a fine warp should be used.
Double Warp Face.—This is the same as “double weft face” weaving, with the exception that two warps are used instead of two wefts. A four and one twill backed with warp is shown at [Fig. 323]. It is necessary to have the warp threads close enough together to hide the bindings. Fancy patterns may be backed with warp by binding the backing warp under warp floats in the face cloth.
