Using both open and filled mesh gaps, the needlework technique known as filet crochet creates a fabric with a lace-like appearance. It is a kind of crocheting in which a grid is formed using a mix of chain and double crochet stitches; the spaces within the grid are then filled to produce a design.

Clusters of double crochet or other crochet stitches are usually worked into the filled gaps, while the free spaces are left vacant. French for "net," the word "filet" describes the resulting fabric's lightness and airiness.

Doily, tablecloth, curtain, and shawl crocheted in filet crochet is a popular ornamental technique. Filet crochet's openwork structure allows for the creation of elaborate patterns and designs.

Filet crochet patterns are typically laid out in a chart format, with each square representing a stitch or cluster of stitches. The design is created by working the stitches into the filled-in squares and skipping them over the open squares.

For those who like working with delicate and aesthetically pleasing textiles, filet crochet can be a gratifying and adaptable technique. .
