WELCOME! In addition to the information that follows, I have a video that covers all the basics of how to corner to corner crochet! Check out the photo tutorials and information below and then head here to watch the video.

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 and design your own if you’re interested. We’ll also cover how to change colors with c2c crochet and how to manage all the different skeins while you’re working.

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 this, but I absolutely love it for the fact that you can design a graph of anything that you want and then essentially paint by number with yarn to turn it into a c2c graphgan. (Graphgan = afghan that’s made from a graph.)

A few years ago, 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 here!

I’ve also used corner to corner crochet to design my Nordic snowflake super scarf, “Be a Deer” afghan and the Free Range Cardigan. As you can see, c2c is a really versatile crochet technique that opens up a whole new world of design possibilities.

How to Crochet a C2C Rectangle

Almost all corner to corner crochet projects are based on a square or rectangle design. Even exceptions like the Free Range Cardigan pattern are still built from several rectangle shapes. So learning how to crochet a C2C rectangle (or square!) is pretty much the most foundational skill you need to master. But don’t worry, we’ll walk through it step-by-step. If you’re a video learner, 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 dimmensions you want for your square or rectangle.

A quick note on increasing and decreasing: In the first stitch of corner to corner crochet, you’re always increasing or decreasing. There’s no such thing as a regular, non-increase or non-decrease first stitch. Decreasing is simply the term for not increasing any more and therefore not making your project any wider/taller on that edge.

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 Nordic super scarf, you might be increasing on one side of the row and decreasing on the other side so as to keep the total number of tiles per row the same.

Here is a step-by-step photo tutorial of the c2c increase stitch with more written details below the photos. Watch a video tutorial on how to increase in C2C crochet here.

How to corner to corner crochet increase stitches to make graphgans from charts. Beginner step by step c2c tutorial from Make & Do Crew.

ROW 1:

Step 1: Chain 6
Step 2: Double crochet into the fourth chain from the hook
Step 3: Double crochet in the next two chain

ROW 2:
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

The “decrease” term can be 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.) Watch a video tutorial of how to decrease in C2C crochet here.

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 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.

I cover all the basics of C2C crochet color changes in this tutorial. You’ll learn the simple methods and “rules” for how to change colors in corner to corner crochet, plus when to cut your yarn and–perhaps most importantly–how to keep all your different skeins under control while you work!

How to Read a Corner to Corner Crochet Chart

Corner to corner crochet graphs can be used to create words, characters and graphic designs. You can even translate a photo, illustration or logo into a c2c graph!

How to corner to corner crochet from a graph chart. Tutorial from

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”–ha! It really doesn’t matter though. If you’re following a graph, the image will turn out the same either way.)

How to read a c2c crochet chart. Learn to make corner to corner crochet afghans in this beginner tutorial.

The increase stitch is worked at the beginning of each row until the longest row in the graph pattern is completed, at which point the decrease stitch is used to start each row. It’s important to note that when working a rectangle graph, there will be a point at which you are increasing at the beginning of every other row and decreasing at the beginning of each of the other rows. This will keep the total number of tiles per row the same. I talk about this a bit more in the How to Corner to Corner Crochet video tutorial.

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: 4B, 17C, 9D, 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.)

How to Design Your Own C2C Crochet Graphs

If you’re anything like me, you’ll get hooked on corner to corner crochet and then almost immediatly want to begin designing your own graphs. C2C crochet is such a great way to create unique designs and personalized gifts and I walk you through every step of creating your own C2C pattern here.

What Yarn is Best for C2C Crochet?

You can really use any yarn you’d like to c2c crochet. I have used Lion Brand Vanna’s Choice for a lot of my graphgan style projects because the color selection is so fantastic and the worsted weight works well for c2c designs. When I’m “illustrating” with yarn, I like to have as many colors in my toolbox as possible and Vanna’s Choice offers over 70 options! Another great worsted weight option with a lot of colors is Lion Brand Basic Stitch Premium and Basic Stitch Anti-Pilling.

You can use any weight yarn to corner to corner crochet though. For example, the cover project from my book, Corner to Corner Crochet: 15 Contemporary Projects, uses Lion Brand Wool Ease Thick & Quick to create a chunky statement piece.

Free Corner to Corner Crochet Patterns

My mom and I have both been whipping up C2C crochet graphgans for a while now, so we’ve got quite the assortment of free patterns to get you started. The Be a Deer Throw is a perfect starter project. (If you work the deer silhouette in one color, you’ll only have two balls of yarn attached at a time.)

If you’d like to try crocheting a C2C garment, the Free Range Cardigan is a surprisingly easy experiment in making your corner to corner stitches form something three dimensional.

And for a super fun, playful C2C crochet blanket, check out the Alpaca Love Graphgan. You can always find all our free corner to corner blanket patterns here.

        I’m new, I haven’t tried c2c it looks easy, I’m just one of those who get a little intimidated until I see it visually how it’s done step by step, cause that’s how I learn 😊 my sister n law, gosh she’s amazing, she made one of her orher family members a c2c graduate Afghan with the year on it. She said its easy to do. I ran across you, & i feel i can learn from your tutorials and the picture step by step instructions!!! I’m just trying build my self up to go forward & try!!🤗😊

    I’m learning the c2c. How can I tell how many boxes I need to start a project? For instance, I plan to make a baby blanket to measure 40×40, how do I input this measurement into the graph? I’d really appreciate your help.

    • Jess @ Make and Do Crew
      May 11, 2017 at 2:38 pm

      Hey Rose,

      I’m sorry for the delay in my response! What I usually do is make a small swatch with the yarn and hook I want to use. Then I measure how big two or three tiles are and then use that to figure out how many tiles I need for the length and width I’d like to make. If you’re using Stitch Fiddle, then you can just input those numbers of tiles to create the graph at the beginning.

      Have fun!

    Hey Jess, thank you so much for your post! I have been having some trouble as I learn C2C that the hole left by crocheting into the turning chain seems more noticeable/larger than yours pictured. Do you have any tips to fix this issue?

    • Jess @ Make and Do Crew
      April 23, 2017 at 2:35 pm

      Hi Kaysi!

      Hmm. I wonder if it’s because your turning chains are kinda loose? Sometimes I find that working three ch alongside dc stitches make the ch just a little taller than the dc. It might help to keep your 3 dc deliberately tighter so that there’s less of a gap created when you work into that space. Does that make sense?

      Best of luck to you!

    I’m learning the c2c. How do I know the right number of boxes to put in a graph for a baby blanket that measures 40×40?

    • Jess @ Make and Do Crew
      April 23, 2017 at 2:37 pm

      Hey Rose!

      How exciting! I’ve loved learning c2c over the past year. If I were you, I’d create a small swatch, maybe something that’s just about 4 rows of c2c. Then I’d measure that to see how wide and tall each of your boxes is. That can give you an idea of how many boxes you’ll need to fill 40×40″. is an awesome site for designing your own graphs if you’re interested too! 🙂

      Turning chain. So essentially, yes. 🙂 It’s the chains that comprise the very beginning of each c2c tile.

    Hi Jess. I wonder if you can help me. I’ve been doing a simple blanket with the C2C techinque. However I can see that the blanket it’s starting to look as if I have added more stitches so the edges aren’t straight anymore. Could you think a reason (apart from the obvious added stitch) that could create this?

    • Jess @ Make and Do Crew
      January 13, 2018 at 4:19 pm

      Hmm. Do you think your gauge is getting looser as you work? If I were you, I’d try counting the diagonal rows to see if you are indeed adding a tile each row or it just looks like that bc your stitches are getting looser or something. The rows should be increasing by one tile per row. 🙂

    January 18, 2018 at 12:21 pm

    Jess— I’m about to start my first C2C project, I’m a little nervous. Question — I crochet left handed, does this affect how/where you start? Would I still be working from the bottom right hand corner of the piece and be going up and out?
    ALSO — thanks for the suggestion about stitchfiddle for photos made into graphs. AWESOME!!!

    • Jess @ Make and Do Crew
      January 22, 2018 at 10:06 pm

      I’m so glad you like Stitch Fiddle. I love it too!

      This is a great question that I might have to research a bit. I don’t think it matters when you’re left handed. I’m pretty sure you can still start at the bottom right. In any case, you can rest assured that it never matters which side of the graph you start on unless you’re using written instructions. If you’re just working from a graph though, you can start in any corner you like. 🙂

    I purchased a C2C pattern but I’m having problems. I contacted the place where I purchased it from but I’m told no one can help me. I understand the increase and decrease of the pattern but for 15 rows I need to have 56 blocks in each row.

    Could you help me with this problem or do you of someone who might be able to help?


    • Jess @ Make and Do Crew
      January 19, 2018 at 3:25 pm

      Hey Kay,

      I’m guessing you need to have 15 blocks in those rows because that helps make the rectangle shape. Is that correct? When you do that you’re usually increasing on one side and decreasing on the other, which makes the total number of blocks stay the same. I talk about that a bit in this video tutorial. I hope that helps!


  • Joyce
    February 23, 2018 at 8:12 am

    This is probably a stupid question but I’m about half way through my first crochet project, a C2C queen size afghan, but before I start to decrease on one side in order to do a rectangle, I want to be sure I have the correct length and width. My question is, where (which side) do I measure the length and width from? I’m a self taught lefty and this is my first attempt so I want to get it right!

    Thank you for any help you can give me.

    • Jess @ Make and Do Crew
      February 24, 2018 at 9:50 pm

      Hey Joyce, I totally understand why this part can be confusing. When you’re at this point, before you’ve decreased at all, you actually can turn either side into the “width” or the “height.” So I’d just choose one to start decreasing on when you’re ready and then keep increasing on the other side until it’s tall enough and then decrease at the beginning of all the rows.

      If that still sounds confusing, I know there are some good Youtube tutorials if you search something like “how to crochet a c2c rectangle.” 🙂

    I am so interested in trying this. Have lots of yarn but haven’t crocheted in awhile. I’m left handed and always get a little paranoid how my projects will turn out. If I follow your instructions as given will it work for a lefty??
    Thanks for the wonderful inspiration you provide. Can hardly wait to get my knitting needles working again too.
