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.
And here are four ways to do the corner to corner crochet stitch

So do you do this for sc too? And when does row 1 start?
I’m confused.
Thank you
Patti
Hi. Please watch video #1; in the first minute, you can see clearly where Row 1 starts. It starts when you create your first block (bundle of stitches), and the second row is two blocks. I hope I have helped. Have a beautiful day, and enjoy crocheting.
If you use single crochet (us term) in corner to corner do you use 3 stitches per block or just the 1 st per block I’m definitely confused
Three SC per block, the same as you would DC. I hope I have helped. Have a beautiful day, and enjoy crocheting.
On the blanket that I’m making, it has 2 corners, 4 rows apart. When do I start decreasing – the first corner or second corner?
If the C2C blanket has two corners, it means it is rectangular C2C. That means you start decreasing on one side, and still increase on the other until you get to the other corner, where you start decreasing on both sides. Please check the video on how to do Rectangular C2C. You must be very careful to start the decreasing on the correct side. If the image becomes distorted, you did it on the wrong side. The best way to know is to check the graph to see exactly where you are, and where the corner is. I hope I have helped. Have a beautiful day, and enjoy crocheting.
