Method and apparatus are disclosed for weaving fabrics on a loom wherein, during the usual operation of the loom, specially arranged warp yarns, hereinafter called "decorating yarns" advancing from separate warp yarn supplies which are remote from the normal warp beam, are caused to cross over the normal warp yarns during shedding. The decorating yarns are under the control of unique heddles mounted in harnesses which are arranged for both sideways or lateral movement and also adapted for up and down movement. The unique heddles and harnesses are controlled in synchronism with the normal shedding of the loom so that the specially arranged decorating yarns are caused to cross over the usual warp yarns and then be projected into the shed to be held in place as the filling is projected through the shed and beat-up. Thus, the decorating yarns, which may vary from the usual warp yarns in any desired manner as, for example, count, color, fiber composition, etc., and may diverse with respect to each other, are locked into the fabric woven on the loom as an integral part of that fabric. Mechanism is provided for programming both the lateral and horizontal movements of the harnesses carrying the unique heddles to permit formation of woven fabrics possessing a wide variety of constructions consistent with the manner in which the aforesaid special harnesses and heddles are operated in relationship to the normal weaving operation of the loom.
