The kloster block constitutes the foundation of Hardanger embroidery. It is worked with satin stitches or straight stitches. Five of these stitches are made to cover four even-weave fabric threads. The block designs thus created are placed along the border of the area that is cut away. The stitches of the kloster blocks serve to hold the threads of the uncut parts of the fabric together.
