Each row lists the tiles in working order, e.g. “3×A, 2×B” means 3 tiles in colour A, then 2 in colour B. The arrow shows the direction of the row on the graph; the number in brackets is how many tiles the row has.
How to make a C2C graph from a photo
- Choose a simple picture. Logos, cartoons, pets on a plain background and silhouettes turn out best. Busy photos lose detail at blanket size.
- Pick the size. More tiles means more detail but more work. 50–100 tiles across suits most blankets.
- Reduce the colours. Start with 4–6 and add more only if an important detail disappears.
- Match your yarn. Tap each colour in the key and change it to your yarn colour to preview the finished blanket.
- Download the graph and the written pattern, and tick off each row as you go.
Reading a C2C graph
Corner to corner is worked in diagonal rows that start with a single tile in the corner. Every row on the graph is one diagonal. The written pattern alternates direction each row, just like you turn your work. For a rectangle, the C2C blanket calculator tells you when to stop increasing.
Frequently asked questions
How many colours should a C2C graph have?
Between 3 and 8 colours works best for most blankets. Every extra colour means more bobbins and more ends to weave in.
Is my picture uploaded anywhere?
No. The pattern is made in your browser, so your picture never leaves your device.
Can I use this for tapestry crochet or pixel blankets?
Yes. The graph works for any square-grid technique; just ignore the diagonal written rows and read the graph row by row instead.
Can I sell blankets made from my graph?
If the picture is your own, yes. Don't use characters, logos or photos that belong to someone else without permission.
