15 Free Corner to Corner Crochet Blanket Patterns You’ll Love

Corner to corner crochet — or C2C — looks fancy, but it is one of the easiest ways to make a blanket. You start in one corner, grow a triangle, then shrink it back down into a square. That is the whole trick.

C2C blankets work up fast. You do not need a super long starting chain. The diagonal blocks hide small mistakes well. And color changes are simple — just switch yarn at the start of a new block.

Below you will find 15 free corner to corner crochet blanket patterns. There are easy beginner throws, sweet baby blankets, and fun picture blankets called graphgans. Pick one, grab your yarn, and start in the corner.

What Is Corner to Corner Crochet?

C2C means you crochet small blocks — usually chain 3 plus 3 double crochet — and join them into diagonal rows. Each row grows by one block until the blanket is as wide as you want. Then you decrease one block per row until you reach the opposite corner.

You only need three skills: chain, double crochet, and slip stitch. If you can do those, you can do C2C. New to the basics? Start with the easiest crochet stitches for beginners first.

Before You Start: 5 Things Beginners Get Wrong

1. Crocheting too tightly. Tight stitches make the edges curl up like a taco. C2C needs relaxed tension so the blocks lie flat. If your work curls, go up one hook size. Let the yarn flow through your fingers.

2. Not knowing when to decrease. This confuses everyone at first. You increase until one side of your triangle equals the width you want. Then you decrease every row. The triangle turns into a square. Measure the long side — when it matches your target width, start decreasing.

3. Losing count of blocks. Each diagonal row has one more block than the last. Count your blocks at the end of every row. A stitch marker in the first block of each row saves you from ripping back later.

4. Running out of yarn. C2C eats more yarn than you think because of the diagonal construction. Buy all your yarn at the start, and check the dye lots match. For a baby blanket you need about 1,000–1,500 yards of worsted weight. For a throw, plan 2,000–2,500 yards.

5. Dreading the loose ends. Color changes leave tails everywhere. Weave each end in as you go — do not save them all for the end. A yarn needle and five minutes per color change keeps the finishing painless. Striped C2C patterns are perfect for using up leftover yarn scraps.

C2C Sizing Cheat Sheet

Each C2C block measures about 1 inch square in worsted weight yarn with a 5.5 mm hook. Count the blocks on one side:

– Lovey / stroller blanket: 25–30 blocks (about 25–30 inches) – Baby blanket: 35–40 blocks (about 35–40 inches) – Lap blanket / throw: 45–55 blocks (about 45–55 inches) – Twin bed blanket: 60–70 blocks (about 60–70 inches) – Queen bed blanket: 80–90 blocks (about 80–90 inches)

Your gauge may differ, so measure your first 6 blocks and do the math. If your blocks are smaller, add more blocks. If bigger, use fewer.

Frequently Asked Questions

Is corner to corner crochet easy for beginners? Yes. You only need chain, double crochet, and slip stitch. Most beginners finish a small C2C square in their first sitting. Start with a washcloth to learn the rhythm.

Why are my C2C edges curling? Tight tension is the usual cause. Relax your grip and try a larger hook. Blocking the finished blanket — pinning it flat and steaming it — also fixes mild curling.

How do I know when to start decreasing? Measure the long straight side of your triangle. When it equals the width you want, start decreasing. Keep measuring every few rows — C2C grows faster than you expect.

How much yarn does a C2C blanket need? A baby blanket needs about 1,000–1,500 yards of worsted weight. A throw needs 2,000–2,500 yards. Buy it all at once so the dye lots match.

Can I make a rectangle instead of a square? Yes. Increase until one side hits your width, then increase on one side only while decreasing on the other. This keeps the width fixed while the length grows. Then decrease both sides to finish.

Do I have to weave in all the ends? Every color change leaves a tail, but you can carry yarn up the side for stripes instead of cutting. For graphgans, weaving as you go keeps the job small. A yarn needle is your best friend.
