Use the filet crochet technique to create filled blocks in crochetwork. In filet crochet, filled blocks create design while open spaces form the background. Blocks consist of 3 double crochet stitches that you can work in the stitches or spaces of the previous row.

1

Crochet the foundation chain: Multiply the number of blocks in the row by 3.

When you read a filet-crochet chart, each block in the chart is actually three stitches. This means that each row of filet crochet has a multiple of 3 stitches plus 1 double crochet at the end to complete the last space or block.

2

Add 3 more chain (ch) stitches for the turning chain.

This turning chain is for the next row’s first double crochet (dc) stitch.

3

To work the first row of blocks, double crochet (dc) in the fourth chain (ch) from the hook.

Double crochet in each of the next 2 chain stitches to complete the first block.

4

Double crochet in each of the next 3 chain stitches to complete the second block.

Repeat this step across the row. You should have 5 blocks at the end of the row (or 15 double crochet stitches, plus the turning chain). You always have 1 more stitch than the multiple of 3.

5

Work the second row of blocks by turning your work.

Each time you turn your work to crochet back across the previous row, a different side of the piece will be facing you.

6

Chain (ch) 3.

This step creates the turning chain for your first double crochet (dc).

7

Double crochet in each of the next 3 double crochet stitches.

You make the first block in this step.

8

Double crochet in each of the next 3 double crochet stitches to complete the second block.

Repeat this step across the row. You should have 5 blocks at the end of the second row.
