WHAT IS FILET CROCHET?
A quick reminder of the basics.
Filet crochet is based on a simple mesh, with the fabric made up of treble stitches separated by chains. The mesh can be formed with either 1 chain or 2 chains between the trebles.
The mesh forms squares and while you’re working, you can either leave the squares open by working chains between the trebles (these are called spaces) or you can fill in the squares by working more trebles (these are called blocks). You can use the combination of spaces and blocks to form patterns, images and lettering. Remember that adjacent squares share the outer trebles of the filet mesh.
Many filet crochet patterns use a chart (as below) rather than fully written- out text instructions, where empty squares represent spaces and dotted squares represent blocks. This saves space and makes filet patterns really easy to follow, whatever your language, and much simpler to work for left-handed crocheters.
