11 Free and Easy Crochet Graphgan Patterns using C2C

Corner-to-Corner (C2C) crocheting is a technique that works rows on a diagonal, usually changing out colors according to a chart or graph.

These types of patterns will always come with the graph if there is a shape design in the middle of it.

However, some C2C patterns are more basic and feature one stitch and color, rendering the need for a graph useless.

Crochet patterns utilizing the C2C method are unique and look different from patterns worked up in standard rows.

The diagonal look not only gives it a non-standard look and feel, but also allows you to take advantage of color changes and detailed patterns in a unique and fun way.

What is Corner to Corner (C2C) Crochet?

C2C Direction

The C2C crochet stitch is a pretty basic concept. As the steps below describe, you follow along with a grid-like pattern in a diagonal row.

You consistently increase your way through the pattern, until you reach the middle, at which point you decrease at the same rate until the end. This is commonly done starting from the lower-right corner, finally finishing in the top-left corner.

  1. The blocks of crochet are slip stitched to three — chain spaces from the previous row.
  2. The increases are made until the width that is wanted is obtained.
  3. After this, the project is decreased back down.

Crochet graphgan patterns can use just about all the yarn types that are available. Just about every yarn can be used to create these blanket designs!

Where Do The C2C Graphs Come From?

This is a good question. No one manually uses a ruler to draw a grid, then individually assigns each cell with a stitch and color.

I use an online tool called StitchFiddle to help take away some harder aspects of creating a C2C pattern. Many times, all you’ll need to follow a graphgan pattern is the diagram – no written instructions needed!

With this tool, you upload an image, then adjust each cell with the click of a mouse to alter its stitch and/or color.

However, getting the colors and stitches right is only half the battle. To get the size right, I use my C2C blanket calculator. This ensures that my number of cells combined with my gauge creates a blanket of the correct size.


The term “graphgan” refers to a blanket – or afghan – that is crocheted using the corner-to-corner method. Since C2C technique uses a graph, and it is being used to make an afghan, the marriage of these two terms created a new one: Graphgan.

This fun term is actually found spelled several different ways across the web. Graphigan, Graphghan and Graphgan all are the same thing.

Anyway, now that you know where this term came from and what it means, let’s move on to finding some fun graphgan crochet patterns.

My Recent C2C Graphgan Patterns

Recently, I created two crochet graphghan patterns using the corner-to-corner method, and I am (pun intended) hooked. I love this method, but the key is keeping track of where you are in the grid.

I print the image of the graph, then mark each cell off with a pencil/pen/marker as I get it done. The sheet becomes a real mess towards the end, but it is essential at keeping me on track. Without it, I’d never be able to correctly create the shape inside.
