What is Corner-to-Corner Crochet?

Example C2C Grid Pattern

Corner-to-corner – abbreviated as C2C – is a type of crochet technique that is a block made up of three chains and three double crochets that work up in diagonal rows. You create little squares that connect and are worked in corner to corner.

You can learn more about the C2C crochet stitch with the steps below.

  • The blocks of crochet are slip stitched to three – chain spaces from the previous row.
  • The increases are made until the width that is wanted is obtained.
  • After this, the project is decreased back down.
  • To estimate the number of C2C squares your project will need, you can use our C2C Blanket Calculator.

Tip: A C2C crochet pattern’s most prominent feature is a grid of squares. This grid will help you identify where you are within the pattern and will let you know if there are any stitch or color changes that are needed. These grids are commonly worked from the bottom-right corner to the top-left corner.

C2C crochet patterns use grids this way because they are trying to create a specific image or shape in the middle of the pattern.

C2C graphs have numbers on all four sides of the grid. These numbers help you count the stitches and keep track of where you are within the pattern.

Creating a C2C Grid

The C2C grids are not created manually. While there are a handful of tools that take care of the hard work for the designer, our preferred on is StitchFiddle. StitchFiddle accepts in an uploaded image and allows you to adjust its size and granularity.

The output of StitchFiddle is a grid like you see in the example grid above.

What Stitches are Used in Corner-to-Corner (C2C) Crochet Patterns?

The most common stitch used in C2C is the double crochet stitch. Occasionally, a C2C crochet pattern will be worked up with half double crochets too.

These are both basic stitches that are easy to learn and fast to work up. Learn more about each stitch below.

Half Double Crochet (hdc):

  • YO (yarn over) insert hook from front to back of the designated stitch, YO the hook and pick up a loop. 
  • YO the hook and pull back through all three loops on the hook.

Double Crochet (dc):

  • Wrap the yarn over (YO) the hook, insert the hook into the specified st.
  • YO the hook again, draw the yarn through the st, so there are 3 loops on the hook
  • YO the hook again draw it through 2 loops, so there are 2 loops on the hook
  • YO the hook, draw it through the final 2 loops.

Chain Stitch (ch):

A simple crochet stitch that often forms the foundation of what crochet stitches are worked into during projects.

  • Make a slip knot.
  • Insert hook into slip knot point first, bring yarn over the shaft of the hook from back to front and grab it with the throat of the hook.
  • Draw hooked yarn through slip knot and onto the hook. This movement will make one chain stitch
  • Repeat steps two and three until you have the desired number of stitches for a pattern. One loop will remain on hook.

More often than not, though, you will see most C2C patterns crocheted with double crochets because it works up faster.

If you are going for a more elaborate design the half double crochet can be used because the blocks are smaller, and it allows for details to show.

Increasing a Corner-to-Corner (C2C) Crochet Project

Step 1: Crochet six chain stitches. Work one double crochet in the fourth (4th) chain from the hook. Work one double crochet into each of the two remaining chains. You have finished one block and the first row of your C2C project!

Step 2: Turn the block to start row two. Chain six

Step 3: Double crochet in the fourth chain from the hook. Work one double crochet into each of the two remaining chains.

Step 4: Skip the next three double crochets from row 1 and slip stitch into the chain 3 space from the first row.

Step 5: Ch 3, next work into the chain 3 space and double crochet three times.

Step 6: Repeat step 2 when starting a new increase row, followed by steps 3 and 4 across the row to the end.

Decreasing a Corner-to-Corner (C2C) Crochet Project

Step 1: When the pattern states to start a decrease (or decrease row) slip stitch across the three double crochet stitches that were just worked. This is usually the halfway point of the project.

Step 2: Next, work 3 chain stitches, make three double crochet stitches in the chain space. Repeat steps 3 & 4 from the increase section across the row.

Step 3: At the end of the row, make a slip stitch into the last third chain space without making a block. Turn the work and slip stitch along the three double crochet stitches to start the next row.

Last Step: Finish with 3 slip stitches along the top of the last 3 double crochets of the last block, and you are done!

Common Corner-to-Corner (C2C) Questions

How Do I Change Colors in Corner-to-Corner Crochet?

It is a good idea to have a section of yarn in a twist or ball separate from the skein if the pattern calls for a change of color.

Separating it will make color changes much easier and less tangled. If needed, you can carry different color yarn strands over the multiple blocks and the yarn will be hidden by crocheting over the strands.

Steps to Change Color in C2C

  1. Finish the block of color you are working.
  2. Drop the yarn and pick up the new yarn color with your hook.
  3. Pull the new yarn through.

How Do I Keep Track of Squares and Diagonal Rows in my C2C Project?

To keep track of rows in your C2C stitch pattern, you will want to have the graph of the project you are working on in front of you as well as the written pattern. This way, it will make it easier to mark off each square as you crochet it.

You may also find that a stitch marker is great to help keep track of the number of squares as well as the beginning of each row too.

What Projects are Best for C2C / Corner to Corner Patterns?

Patterns that are squarer or rectangular work best, such as a crochet blanket, wraps, and pillow covers.

  1. Love the c2 c instructions. I am an experienced crocheter. Your instructions are the absolute easiest to understand. Thank you so much. I am a knitter but love crocheting baby blankets for charity.

    1. Thank you so much, Anne, for your kind words and for taking the time to comment. 🙂
      Happy Crocheting!

  2. Hi. Love your descriptions. Very easy to follow! There appears to be a calculations error with your v2v calculator. For a baby blanket with my guage of 1.5cm x 1.5cm it gives me a result that will see my blanket with a 5.6m width! 🙂 I tried playing around with 2cm and the result is also completely wrong

    1. Thanks for the heads-up on that! I have no idea how my calculations were so off. It’s been fixed now!
