How to do Corner to corner (C2C) crochet – video tutorial

Today, I’d like to show you the basic skills you need to corner to corner crochet, including how to increase, how to decrease, and how to change colors.

Corner to corner crochet (c2c) is a technique that works just as it sounds – you crochet little squares at a diagonal from corner to corner, and increase each row by one square until your project is tall and wide enough, at which point you start decreasing each row.

Corner to corner crochet can be used to make afghans like this: 

You can find those patterns in my Etsy shop, and you can also find a few free C2C graphgans on my blog. (Graphgan = afghan that’s made from a graph.) If you use the discount code: BESTOFCROCHET, you get 20% off. Feel free to use it. 🙂

How to Crochet a C2C Rectangle

Almost all corner to corner crochet projects are based on a square or rectangle design. So learning how to crochet a C2C rectangle (or square!) is pretty much the most foundational skill you need to master. You can find the c2c rectangle video tutorial here.

In order to crochet a C2C square or rectangle, you need to know how to both increase and decrease using the diagonal box stitch. Combining the following two techniques is how you’ll create any dimensions you want for your square or rectangle.

How To Corner To Crochet Increase

Any corner to corner crochet project will always begin with increase rows. You’ll increase by one square per diagonal row until your desired dimensions are reached and then you’ll begin decreasing.

How to Corner to Corner Crochet Decrease

You’ll work the corner to corner decrease stitch as soon as you’ve reached the widest/tallest point in your graph.

How To Change Colors in C2C Crochet

While using one solid color of yarn (or a self-striping cake yarn!) can be a quick and satisfying way to crochet a blanket using the diagonal box stitch, the real fun begins when your design has two or more colors.

All the basics of C2C crochet color changes are covered in this tutorial. You’ll learn the simple methods and “rules” for how to change colors in corner to corner crochet.
