C2C Crochet Instruction
Corner to corner crochet (C2C) is a terrific technique that creates special texture for your crochet project. But it is built based on basic crochet stiches, which makes it very easy to learn. This instruction will show you how to crochet with C2C technique. You will learn how the basic techniques to increase or to decrease in a C2C pattern, how to read a C2C chart, and how to change colors.
With this technique, you start from the corner of a crochet pattern and work towards the other corner by producing diagonal rows of little blocks. You will need to increase each row by one black until it reaches your desired length and width, where you need to decrease each row.
A square or block is the basic unit of a C2C pattern. A C2C crochet project will be a combination of both increasing and decreasing techniques. Any row will start with an increasing square, continue with other increasing squares, and finish with a decreasing technique.
Increase in C2C Crochet
Below is the written and step-by-step photo instruction of how to crochet a C2C increasing square.
Row1 – Square 1 (Pic 1-3)
Chain 6, double crochet into the fourth chain from the hook, double crochet in the next two chains.
You have just finished a basic C2C square. Now, to move on to the next row, you will need to crochet two C2C squares.
Row2 – Square 1 (Pic 4-6)
Chain 6, double crochet in fourth chain from the hook and next two chains, slip stitch to join the previous square
Row2 – Square 2 (Pic 7-8)
Chain 3, make 3 double crochet
The next rows will repeat this technique to increase square (Pic 9).

Decrease in C2C Crochet
C2C decreasing means to stop increasing square, thereby ending the row to move on to the next row.
Below is the written instruction and step-by-step photo (from left to right) of how to crochet C2C decreasing technique.
- You have just finished the final bock of the row
- Slip stitch along the edge (4 slip stitch)
- Chain 3
- Continue making the block as normal

Change Colors in C2C Crochet
When your c2c chart or graph indicates that it’s time to switch colors, you will actually begin the color change in the last double crochet of the original colored tile. These photos illustrate how to change colors in corner to corner crochet, but there are additional written details below.
To change of colors in a corner to corner (C2C) crochet project, do not yarn over the last double crochet of the current square. Insert the new color to yarn over the current square and continue with the next square. Hide the yarn tail inside the block. Please see the photo below for step-by-step instruction.

Note
Don’t carry the yarn too many blocks away as it may be visible and affect the overall look of the C2C project. Normally, I only keep the yarn if the same color is just one block away. Or else, I just cut the yarn and weave it in later.
In the photos below, I pick up nearby green yarn to start a new block. Pic 3 is the wrong side of the crochet project where I hide the green yarn inside the block.

Weave in: Use a small crochet hook or a knitting needle to hide the yarn. Take it through the fibers of the yarn by 4 or 5 opposite directions. For example, the white yarn in the picture below.

How to Read a C2C Crochet Chart
Corner to corner crochet chart starts from the bottom right corner and follows a zig zag way to the top left corner as shown in the example below.
Normally, when you are working on the odd rows (1, 3, 5,…), you are on the right side. When you are working on the even rows (2, 4, 6,…), you are facing the wrong side.

By looking at the chart and counting as you go, you will know how many squares of each color you need to make in each row. You can print the pattern and highlight the row you already finish for easily reading. Be careful on the counting!
A corner to corner crochet pattern may also provide instructions of how many squares of each color you need to make in a given row. It will save your time.
