Cross-stitch is a form of sewing and a popular form of counted-thread
embroidery in which X-shaped stitches in a tiled, raster-like pattern
are used to form a picture. The stitcher counts the threads on a piece
of evenweave fabric (such as linen) in each direction so that the
stitches are of uniform size and appearance. This form of cross-stitch
is also called counted cross-stitch in order to distinguish it from
other forms of cross-stitch. Sometimes cross-stitch is done on designs
printed on the fabric (stamped cross-stitch); the stitcher simply
stitches over the printed pattern. Cross-stitch is often executed on
easily countable fabric called aida cloth whose weave creates a plainly
visible grid of squares with holes for the needle at each corner.
