Cross-stitch
One of my favorite hobbies!
Cross stitch is a form of counted thread embroidery that has been around for ages, and it is one of the easiest forms of hand embroidery to learn. It consists of X-shaped stitches that are used to form a picture.
Cross-stitch is often executed on easily countable fabric called aida cloth. Its weave creates a plainly visible grid of squares with holes for the needle at each corner. Fabrics used in cross-stitch include linen, aida cloth, and mixed-content fabrics called "evenweave" such as jobelan. All cross-stitch fabrics are technically "evenweave" as the term refers to the fact that the fabric is woven to make sure that there are the same number of threads per inch in both the warp and the weft (i.e. vertically and horizontally).
The stitcher counts the threads on a piece of evenweave fabric 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.
