How filet crochet charts work
Filet crochet is worked in thread as a mesh of double crochet posts and chain spaces. On the chart, a filled square is a block (3 dc) and an empty square is a space (dc, ch 2).
Because filet has only two “colors” — filled and open — the generator turns your picture into a two-tone mesh. Pictures with a strong outline read best.
