Tablet weaving is a warp-faced fabric, woven using a set of square cards or "tablets" with holes in their corners. Each set of four warp threads passes through the corners of one card. As the cards are given a quarter turn, one of the threads from the bottom of each set of four will move to the top, and one of the top threads will move down. The weft is then fed through the gap between the top and bottom, and beaten down into place. The next quarter turn exchanges the other pair of threads in each set. As this process slowly twists the warp threads, it is customary to periodically reverse the direction of turning.
