How to Turn a Photo into a C2C or Graphgan Crochet Pattern

A pet, a logo, a favourite place: any picture can become a crochet blanket. Our photo to C2C and graphgan pattern maker turns it into a chart with a colour key and every row written out, for free. The photo stays on your device: your browser makes the chart and nothing is uploaded.

Step by step

1. Choose a photo. Bold, simple pictures work best. Crop busy backgrounds first if you can.
2. Choose C2C or graphgan. C2C is quicker; a graphgan (rows of single crochet) shows finer detail.
3. Choose the size. More tiles across means more detail and a bigger blanket; 60–100 is plenty for most pictures.
4. Choose the colours. Every colour is another yarn; 5–10 usually look best. Turn on “Tidy stray squares” to remove lone dots.
5. Download the chart as a picture and the written pattern as a text file.

Reading the written rows

For C2C, start at the bottom-right corner. Odd rows are read from the bottom end of the diagonal up, even rows from the top down. “Row 12: 3 A, 2 B, 7 A” means 3 tiles of colour A, 2 of B, then 7 of A.
