There are other more advanced techniques in which, instead of merely allowing warp threads to alternate in their up or down positions, individual threads are brought to the surface to form what is called a "pick up" pattern. One side of the band will show the exposed surfaces of warp threads while, on the other side of the pattern, the weft thread will be visible. Using a supplemental weft thread that will come up over the top of certain warp threads, brocaded designs can also be worked into the inkle band.
