If you've ever found yourself intrigued by Corner to Corner (C2C) crochet but felt hesitant to dive in, you're not alone. Many crocheters find this technique intimidating at first glance. But trust me, once you learn the step-by-step process, you'll be amazed by how versatile and fun it can be. Whether you're crafting simple squares, bold geometric rectangles, or intricate patterns, this C2C masterclass will guide you through it all.
Here's a comprehensive breakdown, from making those first few rows to tackling advanced skills like color changes and adding borders. Follow along to level up your crochet game.
What is C2C Crochet?
C2C crochet, or Corner to Corner, is unlike traditional row-by-row crocheting. Instead of working horizontally, you start at one corner of your project and build diagonally across. It’s like watching a staircase grow before your eyes! This technique is perfect for blankets, pillows, and even stylish scarves.

Step-by-Step: C2C Basics
The foundation of C2C crochet is learning how to create and connect the blocks. Each block consists of one chain and three double crochets. Here's how you start:
Growing Your Triangle
- Start with a slip knot and chain 6 stitches.
- Double crochet into the 4th chain from the hook and in the next two chains.
- Congratulations, you've made your first block! Mark the chain 3 space with a stitch marker to keep track.
From here, you'll chain 6 for each new row, build your blocks, and connect them with slip stitches to create a triangular pattern that expands upwards.
Moving into Squares
Once you’ve reached the desired width for your triangle, it’s time to square it off by simultaneously increasing one side and decreasing the other. By adjusting slip stitches, you give your project those flat edges that turn your triangle into a square.

Mastering Rectangles
Want to turn a square into a rectangle? Easy! On one side of your project, keep increasing as usual. On the other, switch to decreasing. Use stitch markers to differentiate the grow side from the stop side.
Having trouble figuring out proportions? Use the "rectangle math" trick: Divide the narrow side of your blanket by three. The result gives you the number of rows you should add to elongate your rectangle. It’s that simple.
Adding Color and Stripes
Changing colors in C2C crochet enhances your project with beautiful patterns and designs. Here's how to manage color changes:
On an Increase Row
Complete the last double crochet of your block up to its final yarn-over, then switch to your new color.
On a Decrease Row
Slip stitch into the joining space, finishing with the new color.
Planning Stripes
Take the time to sketch your design on graph paper. Decide whether you’ll carry your yarn along the project edge or cut and weave in new colors. For seamless transitions, stick to a consistent stripe pattern.

Hook Sizes and Yarn Usage
Not sure what hook to use? Hook size impacts the texture and density of your finished piece:
- 4mm Hook: Creates a tight and sturdy fabric. Great for projects needing structure.
- 6mm Hook: A balance between structure and flexibility.
- 8mm Hook: Produces a softer, looser fabric. Ideal for drapey shawls or soft blankets.
Curious about how much yarn you'll need? Here’s a simple calculation:
- One 100g ball of worsted-weight yarn creates about 2 square feet of fabric.
- For a 6x4-foot blanket (24 sq ft), you’d need 12 balls.
Always keep extra yarn for finishing touches like borders. Check out the C2C Crochet Blanket for more tips.
Finishing with Borders
A polished border can elevate any project. Try a simple single crochet and chain 2 edge. Here’s how:
- Work into the spaces between blocks.
- At corners, add an extra single crochet and chain 2 for a clean, defined edge.
When selecting a border style, consider using a contrasting color or keeping it monochromatic for a subtle finish. Need more border inspiration? Visit the Written Patterns Tagged "C2C".

FAQs
1. What is the best yarn type for C2C crochet?
C2C projects work well with most yarn types, but medium-weight (worsted) yarn is ideal for beginners. It provides good structure and is easy to work with. Softer yarns like acrylic or cotton blends are great for blankets and scarves, while stiffer yarns might suit decorative pieces.
2. How do I manage multiple colors in a C2C project?
To manage multiple colors, plan your pattern ahead using graph paper. Decide if you’ll carry your yarn along the edges or cut and secure each color change. Use bobbins or small yarn balls to keep colors organized and avoid tangles.
3. What’s the easiest way to calculate the size of a C2C project?
Use this simple method:
- Determine the size of one block (a combination of chain 3 and 3 double crochets).
- Multiply the block size by the number of blocks for the width and height. This will give you the estimated project dimensions.
4. Why are my edges uneven in C2C crochet?
Uneven edges happen if you lose track of increases or decreases. Use stitch markers to clearly mark where increases and decreases occur. Check your work frequently to smooth out any mistakes early.
5. Can I use C2C crochet for other shapes besides squares and rectangles?
Yes! While squares and rectangles are common, you can use C2C techniques to create triangles, hexagons, and even pictures by following pixel-like graphs.
6. How do I determine the starting chain length for a specific project size?
Estimate the diagonal measurement of your desired project first. Create a small swatch and measure the size of a few rows to understand how many rows you'll need for the desired project width and length.
7. Do I need to block my finished C2C project?
Blocking is optional but recommended for ensuring straight edges and smoothing the fabric. Use a steam block for synthetic fibers or wet block for natural fibers to shape your project.
8. What’s the trick to maintaining gauge consistency?
Check your tension frequently. Use the same hook throughout the project and avoid crocheting too tightly or loosely. Practice some rows before starting your actual project to get used to the pattern.
9. Can C2C crochet be used for wearable items?
Absolutely! Beyond blankets, C2C crochet is great for scarves, shawls, ponchos, and even sweaters. Just keep in mind to use softer yarns for wearables to avoid stiffness.
10. What do I do if I run out of yarn mid-row?
Join a new yarn by tying the new strand to the old one and weave in the ends securely. Always try to switch yarns at the beginning of a block for less noticeable joins.
