C2C crochet (corner to corner crochet) is a technique where you crochet from one corner to the other, building the fabric diagonally in small squares or blocks.

Do C2C crochet patterns use charts or written instructions?

Often both. Many patterns include a graph (each square equals one square) and/or row-by-row written instructions.

Why is C2C crochet great for bold, graphic designs?

Because the blocks line up evenly, C2C makes it easy to create clean shapes and smooth color changes.

Can I resize these squares?

Yes. Use a smaller yarn and hook for a smaller square, or thicker yarn and a larger hook for a bigger square. Your stitch tension (gauge) will affect the final size too.

Q: Is corner to corner crochet beginner-friendly?

Yes. Many C2C projects use simple stitches (often double crochet) and repeat the same steps as you increase and then decrease.

Q: How do I change colors in a C2C crochet pattern?

Most C2C designs change colors at the edge of a square, which helps keep color blocks neat. If your pattern includes a graph, change colors wherever the graph changes.

Q: How do I join C2C crochet squares?

You can sew squares together, slip stitch them together, or use a join-as-you-go method depending on the look you want.

Q: How much yarn do I need for a C2C blanket?

It depends on the blanket size, yarn weight, and stitch tension. As a quick guide, a baby blanket often takes about 800 to 1,500 yards, a throw blanket is usually around 1,500 to 3,000 yards, and a twin-size blanket can be 3,000+ yards.

Q: What yarn is best for C2C crochet?

For most C2C projects, worsted weight (#4) acrylic or a cotton-blend yarn is a great choice. For coasters and placemats, cotton yarn is usually best because it is heat-resistant and absorbent.

Q: Are these C2C crochet patterns free?

Yes. All of my C2C crochet patterns are free on my blog.

Looking for a fun way to turn simple crochet stitches into bold, eye-catching designs? C2C crochet (corner-to-corner crochet) is a popular technique worked diagonally that builds images using small stitch units called C2C blocks. Those blocks come together to form finished designs known as panels, making this method perfect for clean color changes, graphic shapes, and customizable crochet projects.

On this page, you’ll find free C2C crochet patterns organized by panel size, so it’s easy to choose the right pattern for your project. Make a single panel for a pillow or wall hanging, or combine multiple panels to create a full blanket—it’s completely up to you.

What is corner-to-corner crochet (C2C)?

Corner-to-corner crochet (C2C) is a crochet technique worked diagonally from one corner to the opposite corner. Instead of crocheting long rows side to side, you build the project by adding C2C blocks one at a time, forming the design as you go.

C2C is especially popular for colorwork because color changes are easy to manage and designs are simple to follow using a graph. Once you learn the basic rhythm—increasing, then decreasing—you can use the same steps to make all kinds of projects, from small panels to full blankets.
