Cup stitch is a raised stitch and is used to give three dimensional
effect to the patterns. The first step of the stitch includes creating a
triangle with three long stitches. Each long stitch is then worked with
two twisted buttonhole stitches. To give the stitch a higher accent, the
stitches are built one into other. In the spaces between the previous
row. Continue till the required height. To open the structure, add extra
stitches into some of the spaces. To close up the structure make the
stitches in alternate spaces.
