Cross-stitch is a popular form of counted-thread embroidery in which X-shaped stitches in a tiled, raster-like pattern are used to form a picture. Cross-stitch is often executed on easily countable evenweave fabric called aida cloth. The stitcher counts the threads 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.
Fabrics used in cross-stitch include aida, linen and mixed-content fabrics called 'evenweave'. All cross stitch fabrics are technically "evenweave," it refers to the fact that the fabric is woven to make sure that there are the same number of threads in an inch both left to right and top to bottom (vertically and horizontally). Fabrics are categorized by threads per inch (referred to as 'count'), which can range from 11 to 40 count. Aida fabric has a lower count because it is made with two threads grouped together for ease of stitching. Cross stitch projects are worked from a gridded pattern and can be used on any count fabric, the count of the fabric determines the size of the finished stitching.
