This type of crochet lace is grid-shaped because it uses only two crochet stitches: the chain stitch and the double crochet stitch.

Chain stitches use less thread than double crochet stitches, making a visual difference in appearance between the two types of stitches

Filet crochet forms patterns by filling parts of a chain stitch mesh mostly with double crochet stitches.

This type of crochet is generally constructed from white or raw mercerized cotton crochet thread, and is worked in rows.

Filet crochet is used for decorative applications such as window shades, tablecloths, pillows, coasters and today it is even used in shawls, scarves, dresses and blouses.
