I have an upcoming baby shower and needed to make a baby boy crochet blanket. When I saw the Mandala Baby Yarn in Echo Caves, I knew it would be perfect for such a blanket!
A self-striping yarn with long color changes is perfect for a C2C crochet baby boy blanket. I love a crochet blanket with diagonal stripes, but weaving in dozens of ends from color changes is not my favorite pastime. 😉
The Caspian Crochet Blanket is a colorful, yet simple crochet blanket. You’ll learn how to use the diagonal box stitch to make a C2C crochet pattern rectangle. Then you’ll learn how to add a ribbed C2C blanket border.
C2C Stitch – Corner to Corner Crochet Stitch
Recently I received an e-mail from a crocheter telling me that she looked through all of my free C2C crochet blanket patterns and she didn’t see one with the corner to corner crochet stitch (C2C crochet stitch). I explained to her that C2C crochet is a technique and not a stitch and then realized she was referring to the diagonal box stitch.
I’ve released several corner to corner blanket patterns on the blog using different corner to corner crochet stitches. However, I haven’t shared a pattern for a basic C2C blanket using the most popular stitch pattern, the crochet diagonal box stitch.
This is how the Caspian C2C Crochet Blanket came to be! This beginner C2C crochet blanket will teach you how to C2C crochet. It’s a very basic diagonal box stitch crochet afghan pattern with a ribbed crochet blanket border.
Learn ALL about Corner to Corner Crochet in this crochet article. The article includes several free C2C crochet patterns that use C2C stitch variations.

The Yarn
I chose Lion Brand Mandala Baby in Echo Caves for the easy C2C crochet baby blanket that you see in the photos. This self-striping yarn is perfect for a diagonal box stitch blanket. The long color changes will create diagonal stripes without leaving you with a lot of ends to weave in.
Mandala Baby is a 100% acrylic, DK weight yarn that is currently available in ten beautiful colorways. Echo Caves is my favorite!
Colorwork
I let the colors of Mandala flow the way they came in the cake. When beginning the next cake, I pulled apart the new cake and cut the yarn so that I could begin with the same color as I left off with the old cake. Refer to the yarn label for the order of the colors.
Use ANY Weight Yarn
If you prefer to make a worsted weight crochet blanket instead, no problem! With this corner to corner crochet pattern you can use ANY weight yarn you’d like.
I suggest using a crochet hook that is at least one size larger than the size listed on the ball band of the yarn you choose. Adjust your crochet hook size until you get the drape you’d like for your crochet throw. Gauge is not crucial.

Ribbed Border – Edge #1
Gauge Note & Tip: Exact gauge is not crucial. Simply adjust your hook size so that your ribbed edge lays flat. As you’re working the C2C crochet border pattern, if your ribbed edge becomes wavy, this means that your row height is too tall. Try going down a hook size or two.
Ribbing is approximately 1″ wide.
Set-up: Sl st over to the next corner st.
Row 1 (RS): Ch 5, working into the back hump of the ch, hdc in the 2nd ch from your hook, hdc in each of the next 2 chs, hdc2tog in the next ch & same st as ch 5. Do not turn. (4 sts)

- 2 Stitches Remaining: If you repeat Rows 2 – 3 all the way across an edge of the blanket and have 2 stitches remaining after the last Row 3 repeat, simply repeat Row 2 one more time. Continue to work ribbing along the next edge of the blanket. If this is your final edge, fasten off, weave in ends and block, if desired.

C2C Crochet Blanket Border, Option #2
If you’d like a simpler crochet border for your crochet C2C blanket, follow these basic instructions:
Step 1: Work the section above titled “Prepare Edge for C2C Crochet Border”. This adds a simple single crochet edge to your diagonal box stitch blanket.
Step 2: You can add a simple single crochet border, or use any taller stitch to create a wider border. Using single crochet, half double crochet, or double crochet, simply repeat rounds of crochet stitches. Work as many rounds as you’d like, using the following instructions:
- Work 1 crochet stitch in each stitch along each edge.
- Work 3 crochet stitches in each corner stitch. This will keep your corners from curling.
QUESTIONS CROCHETERS FREQUENTLY ASK ABOUT CORNER-TO-CORNER CROCHET (C2C)
In addition to questions I’ve answered in this article above, below are some commonly asked questions about corner-to-corner crochet.
What is C2C Crochet?
The technique of working corner to corner crochet is very simple. Choose any crochet stitch, begin your project in one corner and crochet on the bias (on a diagonal… think *triangle*), increasing each row, until your project is the desired width and length. Then, decrease each row until you’ve reached the corner opposite the one you started.
What does C2C mean?
C2C is the standard abbreviation for corner to corner crochet.
What is a C2C stitch in crochet?
You’ll often hear others refer to a C2C stitch in crochet. Crocheters call the diagonal box stitch the C2C stitch. This is incorrect! There is no specific C2C stitch. C2C is a crochet technique, not a stitch.
How do you avoid gaps in C2C crochet? How do I make my C2C tighter?
This question is typically asked when crocheting a C2C project with the diagonal box stitch. Each block consists of 3 double crochet and a chain 3. The chain 3 can make your project appear a little holey.
There are two ways to help avoid gaps in your diagonal box stitch projects.
- Work your ch-3 tightly, or
- Instead of a chain 3, work a chain 2. If you choose to use a ch-2 instead, then you’ll begin an increase row with a ch-5 instead of a ch-6. This is also referred to as the C2C 5 2 method.
What size is a C2C crochet baby blanket?
The size of this C2C baby blanket free pattern in the photos is 32″ W x 38″ L, however, you can easily make yours larger or smaller. Check out my Standard Blanket Size Chart, it’s also a great C2C blanket size chart.
You can easily adapt this C2C crochet pattern to make a twin size crochet blanket or even larger.
