Filet crochet

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

[1] Filet crochet is usually constructed from monotone crochet thread made of Mercerised cotton in white or ecru, and worked in rows.

Filet crochet is often used for decorative applications, such as window curtains, tablecloths, and place settings, such as coasters and placemats, but can also be used to create clothing, including yokes, as well as accessories and small bags.

Filet crochet is most often worked from a graph or a symbol diagram.

[2] Filet crochet may also be worked by alternating chain stitches with another type of crochet stitch such as (U.S. terminology) half double or triple crochet, and may be worked from yarn instead of thread.
