Why Learn C2C Crochet?

C2C crochet has a bit of a reputation for being tricky, especially with all the counting and color changes. But once you get over the initial learning curve, it opens up endless possibilities. Whether you’re looking to create a simple baby blanket or a detailed graphgan, mastering C2C can make crochet projects more exciting and full of customization. My tutorial includes color-coded guides, which help you stay on track every step of the way.

The Basics of C2C Shapes

Before you start a C2C project, it's crucial to understand the basic shapes: triangles, squares, and rectangles. Each C2C project is built on these foundations, and knowing how to increase and decrease is key. In this masterclass, you’ll learn how to grow each side, build a perfect square, and even balance a rectangle to fit your specific needs.

Tools You’ll Need for C2C Crochet

Gathering your materials ahead of time will make the entire process much smoother. For this tutorial, I’m using:

• Yarn: You can use any weight or color you like! I recommend a worsted weight acrylic for beginners, but the sky’s the limit. Bright, contrasting colors help keep track of your rows.
• 6 mm crochet hook: This is a great size for most worsted weight yarns, but feel free to experiment.
• Two stitch markers: One to indicate "increase" or "grow" and one for "stop.” If you don’t have stitch markers, a piece of yarn in contrasting colors can do the trick.
• A yarn needle for sewing in your ends once you're done.

Why Are Stitch Markers So Important?

In C2C patterns, it’s easy to lose track of where you are in a project, especially when increasing and decreasing rows. That’s why stitch markers are your best friends here, clearly showing where a row starts or ends. I suggest using green for grow and red for stop — it makes remembering which side does what super simple.

Don’t have stitch markers? No problem. Small yarn scraps in bright colors work just as well.

Getting Started with Your First C2C Row

To kick off your C2C adventure, we always start with a triangle. Begin by making a basic slip knot and then chain 6. This forms the foundation of your first rectangle. Remember, C2C is worked diagonally, so even though it might feel like you’re crocheting rows, you’re actually forming diagonal squares or rectangles.

Once you get the hang of chaining 6 and moving into your foundation stitches, the rest becomes a rhythm. Every first row begins with chain 6, and every following stitch builds on the last. Keep your stitch markers handy to stick in every finished row.

Growing Your C2C Project (Increasing Rows)

As you complete rows, you’ll start to notice a staircase effect forming along one edge of your project. That’s how you know you’re increasing in the proper direction. Remember, increasing is always about adding more “steps” to your staircase and getting wider with every row.

Each new row completes another "block" (three double crochets and a chain). Following the steps for rows 1–5 will build a strong base for whatever shape you plan to crochet.

Changing Colors in C2C Crochet

Most projects use more than one color, especially if you’re working on graphgans or patterned designs. Changing colors in C2C is easy! Simply leave your last double crochet unfinished and pull in your new yarn before completing the stitch. This leaves you with a seamless color change and keeps your edges neat.

If you’re planning to carry yarn along the side, make sure to keep your tension consistent. Loose threads can make your project floppy, while tight threads can warp your design. The trick is to crochet over the yarn you're carrying, hiding it so it’s not visible from the front.

You can see more color-changing tips in my Changing Colors Guide.

Decreasing in C2C (Finishing Your Blanket)

As soon as you reach your desired width, you can start decreasing to finish your project. Essentially, you’ll work in the reverse of what you did to increase. Instead of adding new sections, you’ll slip stitch into existing rows and keep your edges straight.

Pay attention to where your stitch markers are. If you’re following a color-coded project, this is where markers help ensure you don’t make a mistake while finishing the edges.

Still confused? There's a detailed explanation about decreasing rows at the 23:00 mark of the video here.

Easy Stripes and Variations

Thinking of adding striped designs into your C2C project? One practical way to decide on color sequences is to plan ahead using graph paper. This allows you to picture where each color will appear and ensures both sides balance. You’ll want to follow even row counts for each color change, making it easier to return to the same starting point when switching yarn at the end of each pass.

Feel free to explore cool variations of C2C with different color combinations like the Gingham C2C Blanket, which works up quickly and adds a layer of complexity with its join-as-you-go technique.

Calculating Yarn for a C2C Project

Wondering how much yarn you’ll need? Use this simple calculation: most finished C2C squares give you about 2 square feet per 100 grams of yarn. Let’s say your finished blanket needs to be 6 feet by 4 feet — you'd need 12 balls of yarn since 6x4=24, then divide by 2. Always keep an extra ball of yarn handy for mistakes, tight stitches, and decreases, especially if you’re planning a larger border.

Adding Simple Edging to C2C Projects

No crochet blanket is complete without a proper edging or border. After finishing your decrease row, work single crochets into the spaces between blocks all around the edges. This gives a clean, polished look and preps the project for any fancier borders you might want to add.

A good starter edging involves chain 2's and single crochets in the space between your C2C blocks. This sets you up for more advanced borders like bobble edging or complex patterns later on.

Final Thoughts on Mastering C2C Crochet

C2C crochet might feel intimidating at first, but trust me, it’s a technique worth mastering. By learning to visualize each project as rows of diagonal squares, you’ll be able to finish projects faster and more efficiently. And once you've learned how to increase, decrease, and add color shifts, you'll be ready to tackle even complex designs like graphgans.

Frequently Asked Questions About C2C Crochet

What is C2C crochet, and how does it work?

C2C, or Corner to Corner crochet, is a unique technique where you work your project diagonally, from one corner to the opposite corner. It involves creating small blocks that are joined together, making it easy to customize size and patterns.

What materials do I need to start a C2C project?

You'll need yarn (preferably worsted weight for beginners), a 6 mm crochet hook, stitch markers for keeping track of increases and decreases, and a yarn needle for weaving in ends.

How do I change colors in a C2C project?

To change colors, leave the last double crochet of your block unfinished, switch to the new color, and complete the stitch. Ensure you maintain consistent tension to avoid warping your project.

Why are stitch markers important in C2C crochet?

Stitch markers help you keep track of your starting and stopping points, especially when increasing or decreasing rows. Use contrasting colors for easy visibility.

How do I determine the amount of yarn needed for a C2C blanket?

Calculate by dividing the total area of your blanket (in square feet) by the yield of your yarn (approximately 2 square feet per 100 grams). Always keep an extra ball for adjustments and borders.

Can I make different shapes with C2C crochet?

Yes, C2C techniques can be used to create triangles, squares, and rectangles. Mastering the increases and decreases allows you to manipulate these shapes to fit your project needs.

What are graphgans, and how do I make them?

Graphgans are blankets that use graph patterns in C2C crochet to create detailed images or designs. You’ll follow a graph key, working color changes strategically to build your pattern.

How do I finish a C2C project?

Once you've reached the desired dimensions, start decreasing by slip stitching into existing rows, ensuring your edges remain straight and well-defined.
