When the Corner to Corner (C2C) trend first started, I was hesitant to join in – only because it was everywhere.

My very first C2C project was my C2C Poncho (Free Crochet Pattern), which was actually designed for a magazine issue of the C2C theme. For the poncho, I wanted to use C2C stitch pattern in a more out of the box way, and I just LOVE how it turned out! And ever since, I have been hooked.

C2C is such a fun stitch pattern, and perfect for creating patterns and images, especially if tapestry isn’t your thing. These are just a few of my designs: C2C Valentine’s Washcloth, C2C Valentine’s Envelope, C2C Cozy Throw Pillow, and C2C Potted Tulip Square. Check out all my designs HERE.

For this tutorial, I am using Lily Sugar n Cream in Mod Blue, and an H8/5mm hook, and I will be working a rectangle that is 4 boxes wide by 6 boxes in length.

What is Corner to Corner?

Corner to Corner (abbreviated as C2C) is a pattern built on boxes that are worked diagonally, and stacked on top of each other. You begin with the far bottom corner, and one box, then the next row is worked diagonally on top of that with two boxes, then the next row is worked diagonally on top of that with three boxes, and so on until the desired size is reached, then you work less boxes in the same manner to decrease back down to one box, ending at the opposite corner of where you started.

A box is comprised of four double crochet’s.

There are two ways you can C2C with boxes – 1.) in Double Crochet; 2.) in Half Double Crochet. In this tutorial, we will be covering the double crochet version – all you need to know to work this stitch pattern is How to Chain (Photo Tutorial), and How to Double Crochet (Photo Tutorial).

How to Start in C2C:

If you’ve haven’t yet, make a slip knot (photo tutorial), then work a foundation chain (photo tutorial) of 6.

If this was an actual pattern, you would see it written like this: “Chain 6” OR “Ch 6”.

It mostly likely will not tell you to make the slip knot, but you always start with one.

Next, we will double crochet across the chain. Together, this will read in one of these ways:

• Chain 6, DC into the 4th chain from the hook, and each chain across.
• Ch 6, DC into the 4th ch from the hk, and ea ch across.
• OR Make 1 box.

I want to just touch on that last way to read really quickly – some patterns assume you already know how to corner to corner, and will not break it down. Instead, they will just say how many boxes to work and/or the color.

Also, note that the first skipped 3 chains will count as our first double crochet for this box.

Continue to DC into the next 2 chains, and we have one completed box.

How to C2C Row 2 and Above for Increasing:

Row 2 could be written as follows:

• Chain 6, and turn. DC into the 4th chain, and into each of the next 2, slip stitch into the top of the next chain 2. Chain 2, work 2 DC into the space under the same chain joined to, DC into the top of the last stitch. (2 Boxes)
• OR Make 2 Boxes.

In each row that you want to increase, you will begin with a chain 6…

…then DC into the 4th chain from the hook, and across to complete the first box of Row 2.

Now you have a weird looking shape right now – it looks weird, but it’s correct.

Turn the bottom box towards you…

… until it’s mirrored…

… skipping the first three DC from the 1st box…

… insert hook into the top of the beginning chain of the last DC…

… yarn over…

… pull through both the DC and loop on the hook to complete a slip stitch.

We have the first box of Row 2 completed.

To make the next box, begin with a chain 2 (which is equal to a double crochet), yarn over, and take note the “space” that we will be working into.

In my patterns, I call this “the space under the same chain joined to”.

… insert hook into this space, yarn over, and complete the double crochet.

Work one more DC into this space.

For the last double crochet, I recommend working it into the foundation chain on the end (this chain belongs to the 3rd DC of the 1st box from Row 1). By working into this chain, it gives your work a clean edge.

There are two alternatives to this that you may see in other tutorials/patterns:

• Work the last double crochet into the same space as the other stitches, but it leaves a weird gap along the outside edge of the fabric.
• Work the last double crochet into the chain just above where I am recommended, which actually belongs to the chain that we are working around. I don’t like the look as much, plus it takes more effort to work the stitch into this chain because it’s tighter.

Now we have two boxes completed!

In this photo, I worked the last double crochet into the chain of the beginning chain (the last alternative I mentioned) so you can see how it looks. It certainly works, but I like working into the chain below it for an even nicer edging all the way around.

We continue to work in this same manner until we reach our desired size. In this tutorial, I will work until I have four boxes, and I would write it as follows in pattern:

Row 3: Chain 6, and turn. DC into the 4th chain, and into each of the next 2, slip stitch into the top of the next chain 2;
Chain 2, work 3 DC into the space under the same chain joined to, skip the next 3 DC, slip stitch into the top of the next chain;
Chain 2, work 2 DC into the space under the same chain joined to, DC into the top of the last stitch. (3 Boxes)

Row 4: (I) Chain 6, and turn. DC into the 4th chain, and into each of the next 2, slip stitch into the top of the next chain 2;
(II) [Chain 2, work 3 DC into the space under the same chain joined to, skip the next 3 DC, slip stitch into the top of the next chain] 2x;
(III) Chain 2, work 2 DC into the space under the same chain joined to, DC into the top of the last stitch. (4 Boxes)

If you wanted to work more than 4 rows of increases, you would just work more repeats in the section I have labeled as (II) in Row 4.

I have a tip for you! Sometimes as you work, it’s easy to accidentally catch the yarn of the box above you with your crochet hook.

To avoid this, I just fold the fabric down…

… and hold it in place as I work.

And here is 4 rows completed. Remember they are read diagonally. Row 4 has 4 boxes.

How to Keep the Same Number of Boxes without Increasing or Decreasing:

Once we reach our desired width – in this case 4 boxes wide, we stop increasing in the width.

Remember before that I said I would be working a rectangle that is 4 boxes wide by 6 boxes in length. To achieve this, we will not increase the width, but we will increase the length, and I will show you how!

If you were making a square, you would skip this part, and begin decreasing.

We are not increasing the width anymore, so chain 1…

… and turn.

Skip the first stitch, slip stitch into the 2nd…

… 3rd and 4th stitches.

Now we’re in place to begin the first box of Row 5. Chain 2…

Work 3 DC into the space under the same chain joined to, skip the next 3 DC, slip stitch into the top of the next chain,
(chain 2, work 3 DC into the space under the same chain joined to, skip the next 3 DC, slip stitch into the top of the next chain) 2x,
Chain 2, work 2 DC into the space under the same chain joined to, skip the next 3 DC, DC into the top of the last stitch. (4 Boxes)

Remember we want 6 boxes in the length, and we now have 5, so to continue to increase the length, we will begin with a chain 6…

As we follow in pattern, make sure you are only working 4 boxes in total for this row (we aren’t increasing the width anymore).

Now take notice that we have reached 6 boxes in length. Next, we will decrease down to close up that gap.

If you wanted to make it longer, you would continue repeating the last two rows, one beginning with a slip stitch over, and one beginning with a chain 6.

How to Decrease in C2C:

Now, we want to decrease by one box in each row back down to 1 box, so we will start every row with a slip stitch over, and end each row in line with the 6th box.

Row 7: Turn. Slip stitch into the 2nd stitch, and each of the next 2. Chain 2, work 3 DC into the space under the same chain joined to, skip the next 3 DC, slip stitch into the top of the next chain,
(IV) (chain 2, work 3 DC into the space under the same chain joined to, skip the next 3 DC, slip stitch into the top of the next chain),
Chain 2, work 2 DC into the space under the same chain joined to, skip the next 3 DC, slip stitch into the top of the last stitch. (3 Boxes)

If you had more boxes in the width, you would continue working in the same manner repeating (IV) one less time each row to decrease the number of boxes by one each row.

Row 8: Turn. Slip stitch into the 2nd stitch, and each of the next 2. Chain 2, work 3 DC into the space under the same chain joined to, skip the next 3 DC, slip stitch into the top of the next chain, chain 2, work 2 DC into the space under the same chain joined to, skip the next 3 DC, slip stitch into the top of the last stitch. (2 Boxes)

Row 9: Turn. Slip stitch into the 2nd stitch, and each of the next 2. Chain 2, work 3 DC into the space under the same chain joined to. Skip the next 3 DC, slip stitch into the top of the last stitch. (1 Box)

Fasten off, weave in your ends, and you have a finished rectangle!

I have a photo tutorial coming with how to C2C in HDC (half double crochet), and soon I will share how to add a border to your C2C projects.
