This free crochet pattern is for a basic, chunky, beautifully textured corner to corner afghan. Worked in two strands of worsted weight yarn (or one strand of chunky weight yarn), this cozy afghan works up fairly quickly.

As I was working on my Blessed C2C Afghan, I figured a basic corner to corner afghan pattern with actual instructions would be a good place to start and a good resource that I could refer back to.
My afghan is worked in a solid color, but you could use some Caron Cakes yarn (or similar) for an easy, colorful afghan, or change colors as you see fit through the pattern. Also, I used two strands of worsted weight yarn held together for my afghan, but you could use one strand of a chunky weight yarn.

Materials:
- 2960 Yards of Worsted Weight Yarn – I used about 8.33 (1/3) Skeins of Hobby Lobby’s I Love This Yarn in the Ivory colorway
- M13/9mm Crochet Hook
- Tapestry Needle for Weaving in Ends
Material Notes:
For this afghan, two strands of worsted weight yarn are held together. In it’s place, you could use one strand of chunky/bulky (#5) yarn. Take a gauge. If you don’t mind a slight difference in measurements, gauge isn’t essential. You could even go up a hook size, and use super bulky yarn for a larger afghan.
Yarn Alternative: Red Heart With Love
Time Spent:
This afghan works up in just over 11 hours.
Measurements:
- Before Border, 37.13 (1/8″) Wide by 43.5″ Tall;
- With Border, 42.25″ Wide by 47.75″ Tall – this is a little larger than a toddler/child size afghan, and a little smaller than the standard throw blanket size.
Gauge:
11 DC by 6 Rows = 5″ by 4.5″
Abbreviations (US Terms):
- C2C [in DC] – Corner to Corner in DC (Photo Tutorial)
- DC – Double Crochet (Photo Tutorial)
- SC – Single Crochet (Photo Tutorial)
- HDC – Half Double Crochet
Pattern Notes:
This blanket grows from the bottom left corner up to the top right corner.
Beginning chain 2 counts as a double crochet.
A box is comprised of four double crochet’s.
The “space under the same chain joined to” is defined as the space between the last two double crochets of the previous rows box. Working the final double crochet into the top of the chain from the previous row helps to keep the edge more even. After completing the first box, you may also need to lightly tug on it to keep it even as well.
I highly recommend weaving in your ends as you go. It will be easier to access the spots while you are near them. While there technically isn’t a right or wrong side with corner to corner as it is worked turned the whole time, I still view it as odd rows being the right side, and even rows being the wrong side. I suggest using a smaller crochet hook to bring all of your ends to the wrong side, and weave in on this side only. Also by weaving in one end (of the two from doubling your strands) at a time, and the second in a different spot, you eliminate extra bulk.
In Border, chain 1 does not count as a stitch, and join to the first stitch.

Pattern:
Chain 6. DC into the 4th chain, and into each of the next 2. (1 Box)
Row 2: 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)
Row 3: (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;
(III) Chain 2, work 2 DC into the space under the same chain joined to, DC into the top of the last stitch. (3 Boxes)
Rows 4 – 38: Using Row 3 as a base, you will continue working in the same manner repeating (II) one extra time each row to increase the number of boxes by one each row. At the end of Row 38, you will have 38 Boxes.
At this point, if you want a wider blanket, you can easily continue increasing until you have reached your desired width. Keep in mind, that given border will also add a little over 4″ to the width and height.
Row 39: 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 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) 36x;
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. (38 Boxes)
Row 40: 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) 36x;
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. (38 Boxes)
Rows 41 – 42: Repeat Rows 39 + 40.
At this point, if wanted a taller blanket, you could continue repeating Rows 39 and 40 until you’ve reached your desired length. Keep border in mind.
Row 43: 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) 35x;
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. (37 Boxes)
Row 44 – 77: Using Row 43 as a base, you will continue working in the same manner repeating (IV) one less time each row to decrease the number of boxes by one each row. At the end of Row 77, you will have 3 boxes.
Row 78: 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 79: 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)

Border: Chain 1. SC into the space between the boxes just behind your current place, chain 2, (SC into the space in between the next 2 boxes, chain 2) 36x, SC into the corner stitch, chain 2, (SC into the space in between the next 2 boxes, chain 2) 41x, SC into the corner stitch, chain 2, (SC into the space in between the next 2 boxes, chain 2) 37x, SC into the corner stitch, chain 2, (SC into the space in between the next 2 boxes, chain 2) 41x, SC into the next corner stitch, chain 2. Join. (160 SC)

Your blanket is beautiful !!!!
Thanks for your visit !
Have a nice week !
Anna
Thank you so much! I really love the solid look of the corner to corner technique.
Gorgeous blanket! I am in awe of your talent girlfriend!!
Thanks so much! Likewise with your recipes!
I love c2c crochet, it works up so quickly and is great for multitasking when watching tv. This is lovely with that pretty border.
There isn’t much crochet projects I don’t find great for multitasking when watching tv, hehe. Thanks for stopping by 🙂
I love that pattern, thank you for sharing at The Really Crafty Link Party this week. Pinned!
Thanks, Teresa!
Can this be worked with one strand?
Love the border.
Absolutely! I chose double strands of worsted weight yarn so it creates a chunky weight yarn so it works up faster, but you could work in one strand of any weight yarn. You’ll just keep increasing until you’ve reached your desired height (keep in mind the border will add some height to it), and then work across until you’ve reached your desired width (same with border).
My first time trying out the C2C pattern – this is a great help!
Thank you!!!
So glad I could help! I also have a C2C photo tutorial if you need: https://eyeloveknots.com/2020/06/how-to-corner-to-corner-c2c-in-double-crochet-dc-photo-tutorial.html
Let me know if you have any questions 🙂
How many boxes did you end up with? Trying to use this for a temperature blanket using bulky yarn. I’m counting 1596. Does that seem right?
I just counted and got the same number of boxes as you.
If you add 6 more rows to the length (38 boxes each row), you would get 1824 which is 1 box short of 365 five times, and the 1 could be represented by the border.
