What Is Filet Crochet? A Beginner's Guide
Written by the Filet Crochet Chart Builder team · Updated
Filet crochet is a grid-based technique that builds a design out of just two units: a filled block and an open square of mesh. Because every square is one or the other — never half-filled — a filet pattern reads exactly like a chart, which makes it one of the most approachable ways to crochet a picture, a name, or a border.
Blocks and mesh
Every square in a filet design is either a block (filled solid) or a space (open mesh). An open square is typically a double crochet, two chains, then two skipped stitches; a block fills that same width with double crochet instead. Lined up across rows, those filled and open squares form the image — the dark cells of a chart are blocks, the light cells are mesh.
Only two stitches to know
Almost all filet crochet uses just the double crochet and the chain. Once you can work a dc and a ch and count to two, you can follow a filet chart. There is no colourwork to manage and no fabric to read — the structure of the mesh itself carries the design.
Why it suits charts
Because a square is strictly on or off, a filet chart is unambiguous: what you see on the grid is what you crochet. That one-to-one relationship is why filet is a natural fit for monograms, hearts, animals, and lettering, and why a charting tool can hand you a pattern you can follow square by square.
What you can make
Filet is traditionally used for curtains, table runners, and doilies in fine cotton thread, but the same charts work in heavier yarn for blankets, cushions, and bags. The technique scales: change the yarn and hook and the design grows or shrinks without any change to how you read the chart.
