How to change colours by crocheting the C2C method

A colorful crocheted blanket depicts a cheerful unicorn with a rainbow mane, surrounded by stars on a bright blue background. The scene is playful and vibrant.

A warm welcome to you! 🥰

Corner-to-corner (C2C) crochet is a truly magical technique. It offers endless possibilities to create beautiful and detailed crochet pieces — from cosy blankets and pillows to stylish table runners and sweaters.

Whether you're just starting your crochet journey or you're a seasoned crocheter looking for something new, the C2C method is perfect for you. It’s easy to learn and fun to follow using simple charts. Anyone can master C2C — really!

In previous posts, you've already learned how to make a chain stitch, crochet a chain and double crochet, and how to work the C2C technique using just one colour. Now, let’s take the next step and learn how to change colours in C2C crochet.

In the latest posts, you have already learned how to make a chain stitch, chain and double crochet, and even how to crochet the C2C method in one colour. Today, let's go a little further and learn how to change colours when C2C crochet.

Three small stuffed hearts are beside it, creating a cozy, handmade feel. A square crocheted potholder featuring a blue and gray checkered heart on a white background, with a deep blue border, conveying a cozy, handmade feel.

Let's get to work 🙂

I'll show you how to change colours in C2C crochet using a pattern and a description — pick whichever way works best for you!

  • GRAPH - shows us which way to crochet

  • DESCRIPTION - The row is a row

B - Blue

N - Navy

"Text chart with knitting pattern instructions. Rows 1-25 detail stitch sequences, including increases and decreases, using abbreviations like B and N."
Work begins from the left corner. Only one colour is used from rows 1 to 8, so the process is straightforward.

Everything goes smoothly until we change colour :)

It's not that hard, no worries. As the saying goes: "The Devil is not so black as he's painted". 

The yarn in the new colour (in this case, navy) is taken and pulled through the spot where the crochet hook was previously inserted to make the next square.

Crocheting C2C methods - one colour

Two gray knitted pillows with wooden buttons are neatly placed on a textured gray and black patterned bedspread, creating a cozy and elegant bedroom setting.

Welcome back, yarn lover! 🧶

If you’ve never heard of C2C crochet before – don’t worry, you’re not alone! But today’s the perfect day to dive in and see what all the fuss is about 😄

C2C stands for corner-to-corner – and yep, it’s exactly what it sounds like! It’s a fun and clever way to crochet from the bottom-left corner of your project all the way up to the top-right corner.

It’s a bit like building pixel art, kind of like in Minecraft 🎮. Only here, instead of blocks, you’re using cosy little squares made of yarn.

I’ll walk you through how it works so you can start your first C2C project with confidence (and maybe even a little excitement)! 💪✨

In this post, I’ll show you how to start crocheting using the C2C (corner-to-corner) method with just one colour of yarn 🎨

Here’s what you’ll need:

  • a crochet hook (check your yarn label for the recommended size) 🧶

  • scissors ✂️

  • a yarn needle with a large eye 🪡

Before you begin, make sure you’re comfortable with these basic stitches:

  • chain stitch

  • double crochet stitch

  • slip stitch

Need a refresher? You can find my beginner-friendly tutorial “Basics for C2C Crocheting – Chain, Double Crochet & Slip Stitch” right here on the blog! 😊

In my projects, I use:

  • GRAPH - shows us which way to crochet

  • DESCRIPTION - the row is a row (P - Purple)





Catch the yarn with a hook and move the crochet hook towards the 3rd chain stitch
