Corner-to-corner, also known as C2C, is a box stitch technique crocheted in diagonal rows from one corner to another. This tutorial focuses on the double crochet version.
Corner to corner is a very popular technique to turn pixel graphs into pictures and then crochet them into blankets, pillows and so much more.
Although it may seem confusing at first, it’s actually very easy once you understand the concept and practice.

All you need in order to follow along with this tutorial is yarn and a hook. So go grab that and start with the tutorial.
Before we get started though, I would like to explain to you the basic foundation chain for the C2C. It is the box stitch (chain + 3 stitches) connected with a slip stitch.
How to read the pixel graph for C2C
To explain, the squares aka pixels are created in diagonal rows as you can see in the picture below. The pink bottom left graph shows the order in which square is created first and which one next.
Although the pixel graph is not shown in the right orientation, it’s still correct. Typically graphs are worked from the right bottom corner – first pixel and first box stitch – to the top left corner – the last box stitch and pixel of the graph.

Corner-to-Corner Picture Tutorial using DC’s
This tutorial is written in US terms.
In the below tutorial I used dc’s explained and demonstrate the C2C stitch pattern.
Increasing in C2C
1. Make a chain of 6
2. Crochet 1 dc in each of the 4th, 5th, and 6th chain from the hook
3. Now, create another chain of 6 (you always do that when increasing at the beginning of each diagonal row)
4. Crochet 1 dc in each of the 4th, 5th, and 6th chain from the hook (picture on the left) and then flip the first square over (picture on the right)
5. Next, you will slip stitch to the space where you see the 3 chains (of the chain of 6 that you did not crochet into)
6. As we are not done with the 2nd diagonal row yet, you will crochet a chain of 3 (you will always do that on the squares where you do not increase or decrease)
7. Next, crochet 3 dc’s in the same space where you slip stitched into
8. Now you finished row 2 and will work on row 3 which means you will need to increase again by chaining 6
9. Crochet 1 dc in each of the 4th, 5th, and 6th chain from the hook (picture on the left) and then flip your work over (picture on the right)
10. Now slip stitch to the neighboring square (into the chain 3 space) which you see on the left picture, chain 3, and crochet 3 dc’s and slip stitch again to the neighboring square (right picture)
11. Chain 3, crochet 3 dc’s to finish the 3rd row
Decreasing in C2C
12. For this example, we will now decrease, but you could also now continue to increase and make the Corner-to-Corner bigger. In order to decrease, ch 1, and slip stitch into each dc and chain 3 space you just created
13. As we now work on row 4, chain 3 and crochet 3 dc’s in the same space
14. Chain of 3 and crochet 3 dc’s in the same space and slip stitch to the neighboring square
Now you finished your first small Corner-to-corner square. Just to recap, anytime you start a row, you chain 6 (remember it is a different number for hdc’s and tr’s). When you continue in a diagonal row, you create a chain of 3 at the beginning of each square/pixel and when you decrease, you create a chain of 1 and slip stitch into the stitches and space you just had created.
More C2C versions
In order to create a Corner-to-Corner, let’s say blanket, in either half double (hdc), double (dc) or treble crochet (tr), please follow this formula below.
The foundation chain has 3 chains to which you add:
- 2 chains for hdc (to make 5 chains), aka MINI C2C -> Tutorial is here
- 3 chains for dc (to make 6 chains)
- 4 chains for tr (to make 7 chains)
You could do the same for single crochets (sc), but it will most likely not look like a square in the end.
You can now create pixel graphs and blankets using the Corner-to-Corner stitch pattern. It is an easy and fast way to create beautiful blankets with lots of texture. Your imagination is endless and therefore you can create as many blankets as you which using this technique. How cool is that?
