Learn all the essentials of how to corner to corner crochet including c2c increases, c2c decreases and how to read a graphgan chart.
A couple of years ago I stumbled across
Corner to corner crochet (c2c) is a technique that works just as it sounds–you crochet little “tiles” at a diagonal, increasing each row by one tile 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 striped afghans like
Last year, I took on the (overly?) ambitious project of designing a corner to corner crochet Christmas afghan for my family. While it was quite a big project, we love how it turned out and will use it for years (hopefully even decades!) to come. (You can find all the free patterns
I’ve also used corner to corner crochet to design my
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 read a c2c chart. Later this week, I’ll share how to change colors with c2c crochet and how to manage all the different skeins while you’re working.
A quick note on increasing and decreasing: In corner to corner crochet, you’re always increasing or decreasing. There’s no such thing as a regular, non-increase or non-decrease stitch. Decreasing is simply the term for not increasing any more and therefore not making your project any wider/taller.
How To Corner To Crochet Increase
Any corner to corner crochet project will always begin with increase rows. You’ll increase by one tile per diagonal row until your desired dimensions are reached and then you’ll begin decreasing. It’s relevant to note that if you’re making a rectangle, like I did in my
Here is a step-by-step photo tutorial of the c2c increase stitch with more written details below the photos.
Step 1: Chain 6
Step 2: Double crochet into the fourth chain from the hook
Step 3: Double crochet in the next two chain
Step 4: Chain 6
Step 5: Double crochet in fourth chain from the hook and next two chains
Step 6: Slip stitch into the ch-3 turning chain from the previous row
Step 7: Chain 3
Step 8: Double crochet 3 in ch-3 turning chain
ROW 3 and beyond:
Repeat steps 4-8
How to Corner to Corner Crochet Decrease
I find the “decrease” term slightly confusing because when this stitch is worked, the row doesn’t actually look as if it’s decreasing. Instead, it looks like a flat edge. In reality, the decrease stitch is eliminating one tile from each row you’re crocheting. (See how the top edge and the right side edge are flat as the last section of the square is built below? That’s thanks to the decrease stitch.)
You’ll work the corner to corner decrease stitch as soon as you’ve reached the widest/tallest point in your graph.
Here is a step-by-step photo tutorial of the c2c decrease stitch with more written details below. (In this example, my desired graph would only be three tiles wide. So when I reached the third tile, I would begin to decrease so as not to make the project any wider.)
Step 1: Instead of chaining 3 as you usually would, slip stitch in each double crochet
Step 2: Slip stitch into ch-3 turning chain
Step 3: Chain 3
Step 4: Double crochet 3 in ch-3 turning chain of previous row.
How to Read a Corner to Corner Crochet Chart
Corner to corner crochet graphs can be used to create words, characters and graphic designs. Using
Corner to corner graphs are typically worked from the bottom right corner to the top left corner as illustrated in the diagram below. (I didn’t know this at first though and worked my entire first c2c project “backwards”–it really doesn’t matter though. The image will turn out the same either way.)
Some corner to corner crochet projects include written instructions that tell you how many tiles of each color to work in a given row. (They would look something like Row 17: 4 B, 17 C, 9 D, with each letter representing a different color of yarn.) Written c2c instructions are really helpful because the prevent you from needing to do a lot of counting on the graph.
I tend to be sort of a “map reader” crocheter though so I really like to look at charts and graphs. When working a corner to corner chart, I like to use a ruler and pencil to draw lines diagonally through each row. Then I highlight each row after I complete it so that I easily know where I’m at in the graph.
When in doubt, count your tiles! It’s a real bummer to get further along in the project and realize you made an error with one tile a ways back. (Trust me, I did this last night. So. much. frogging.)
