Aida is a fabric used in cross stitch. Usually the sizes are given in a "stitches per inch" format. Usual sizes are 7,10,11,12,14,and 18 stitches per inch. This fabric has a distinct weave to it that allows for easy counting and consistant stitch size. Each stitch is made over a square that is woven into the fabric.
