How to C2C Crochet Tutorial + Video Tutorial!

C2C crochet is a different technique of crocheting where you work in diagonal rows instead of the regular horizontal rows. This style of crochet really took off a few years ago and it’s still really popular, especially for crocheting blankets. With C2C you can work graphgans and images into your blankets easily and customize them with anything you like. I have a few C2C patterns available already, but today, I want to share with you a simple C2C crochet tutorial. So let’s get started!

How to C2C Crochet Tutorial + Video Tutorial!

If you didn’t already know, C2C stands for “corner to corner”. That’s because these patterns don’t work back and forth along a horizontal or even vertical axis. Instead, you are working diagonally. You start at one corner and extend each row until you get to the width that you want. Then, you start decreasing until you get to the opposite corner. For this C2C crochet tutorial, I’ll be working on a small sample square of 14 by 14 blocks. This is just one of the blocks for a blanket pattern I have coming up soon so stay tuned for that by subscribing to the newsletter here or at the bottom of this post.

  • ch – chain
  • DC – double crochet
  • sl – slip stitch

How to C2C Crochet: Tutorial with Video

For this sample, I’m using a DK weight yarn in Bernat Baby Coordinates and a 5.00mm crochet hook. You can work this pattern with any hook and yarn size you want though. 

1. First, make a slip knot and chain 5.

2. YO and double crochet into the 3rd space from the hook and each space after. You’ll have 3 DCs and a chain 2. 

That’s the first block done and it makes up that first corner.

How to Increase

Next, we’re going to learn how to increase for each of the next rows. Working in C2C is really just as simple as learning how to see the rows as a series of blocks rather than individual stitches.

3. Chain 5 to start the next row and DC 3 starting from the 3rd space from the hook. This is the first block of the second row.

4. With the two blocks stacked on top of each other, rotate the bottom one so that the ch 2 space lines up with where your hook is now. Slip stitch to the chain 2 space of the last row. This brings the two blocks together. Then chain 2 and work 3 DC into the chain 2 space to form the next block.


See how you increased the row by 1 block? The first row had just the 1 block and the second row has 2 blocks.

For row 3 and each increasing row after, you’re going to do the same thing.

Chain 5,  and  DC 3 starting from the 3rd space from the hook. Rotate the work and sl st to the top of the ch 2 space of the last block.

*Ch 2, DC3 into the chain 2 space, slip st to the top of the next block*. Repeat from * to * until the end of the row.

Rotate the work to start the next row the same way.

The chain 5 at the start of each row increases each row by one block. You can continue this way until your project is as wide as you like, then you can start decreasing. For this square, I worked for 14 rows, then switched to the white yarn for decreasing.

How to Decrease

To decrease in C2C, you don’t really decrease; you just stop increasing.

1. Slip stitch 3 times into each of the next 3 spaces. Because you didn’t chain 5 and work the DCs, you didn’t add another block. Instead, you flattened that side to create the top edge of the piece.

2. Now, it’s business as usual. Work the rest of the row the same way you’ve been working this entire time. But instead of working the last block, your row ends when you slip stitch to the top of the last block.

Then, turn the work and repeat rows 1 and 2 to decrease each row by one block until you only have 1 block left.

See how easy that is? Once you know how to make the blocks, it’s just a matter of building the blocks up and making the blanket wider. When it’s wide enough, you stop adding and just continue with one block less in each row until you have the finished square. Then bind off as usual and you’re done!

How to Read C2C Patterns

Crochet patterns usually write out the full steps and the stitches you need to work for each row. With C2C patterns, though, that’s not the case. Some designers will include the instructions on how to the first few blocks, but since the pattern is pretty much always the same, you’ll have color charts instead.

This is basically just like drawing something in graph paper and giving each color a full block. The charts tell you when you change color and how many blocks of color A should be in one row, then how many blocks of color B, etc.

Take a look at this graph below.

You’re starting at the bottom left corner and working up to the top left. You could work on a C2C chart from any corner, but this is the easiest way for me. 

The first 12 rows are all works in white, so no trouble there. Row 13 has some color involved though so it would be written as something like this:

Row 13: 2W, 9R, 2W – each letter represents the color to use and the total number of blocks equals the row number. It helps to have a ruler and cross off rows as you work through the chart so you don’t get mixed up.

And that’s all there is to this C2C crochet tutorial! Give this little heart sample a try and let me know how you get on with it. Be sure to also watch the video if you need helping seeing how the blocks turn and join to each other. It may sound confusing but it’s very easy once you actually pick it up and start working. You can also check out some of my other C2C blanket patterns down below. The one I’m working on in the video will be up soon too!

The 3O had me baffled on row 8 until I FINALLY realized is it "O" for orange and not a zero!! Instructions for C2C would be much more clear if you had a row 3 and row 4 illustration.

Thanks for the feedback. I'll be redoing this tutorial and will hopefully have a video and better pictures to go along with it!

Between the increase and decrease how do u do the rows that stay the same number of blocks.

Shehla Ahmed

For the rows that stay the same, you actually just work a decrease every other row. Because it's worked on a slant, one side will increase, but the next row will decrease only on the one side, so you get a section that stays the same in the end. It sounds a bit weird but it works!

I know this is really old, but I have a question. When decreasing, does the 3 slip stitches to flatten the side count as a stitch? Or does just the stitch after that count as the stitch?

The 3 slip stitches don't count as a stitch. They're just to get you in the right spot for the next stitch.

You lost me!! I did the first corner and the first block, but I don't see what you mean by step 5 of 'how to increase'. What chain 2 space of last row? The photo is confusing me further. I think a video might be more helpful for me.
