If you started learning C2C crochet increase and noticed your project turning into a triangle… you might have paused and wondered:
“Wait… did I do something wrong?”
You didn’t. In fact, that triangle shape is exactly what should be happening.
Today we’re going to walk through why C2C crochet starts as a triangle, what it means, and how this step builds the foundation for everything you’ll make moving forward. We will also increase rows on your previous triangle.
Why Does C2C Crochet Increase Form a Triangle?
C2C crochet is worked diagonally, not in straight rows like traditional crochet. That means each new row grows in a slightly different way. Instead of keeping the same number of stitches across, you are adding one new block(bump as I like to call it) at the beginning of every row.
And that’s what creates the triangle.
Each row gets wider than the last. One block, two blocks, three blocks…..and on. As those rows stack diagonally, your project naturally forms a triangle shape.
So if your piece looks like a triangle right now… YOU’RE DOING IT RIGHT!
What Does “Increasing” Mean in C2C?
In C2C crochet, increasing simply means adding one extra block (bump) at the beginning of each new row.
That extra block is what allows your project to grow wider. Each time you:
- Chain
- Turn
- Create a new block before joining the previous row
…you are increasing.
There’s no complicated math or counting patterns to memorize. You’re just repeating the same simple step at the start of every row.
Why C2C Crochet Increase Matters
This increasing stage is more than just shaping your project.
It’s where you:
- Build consistency in your stitches
- Get comfortable with the rhythm of C2C
- Start to see visible progress
And honestly, that progress is one of the most encouraging parts. With every row you add, your triangle grows. You can actually see your work expanding, which makes this a really satisfying stage for beginners.
Give Yourself Grace While Learning C2C
If your triangle looks a little uneven, your edges aren’t perfectly straight, or your tension feels slightly off, guess what?
That is completely normal. You are learning a new movement. Your hands and brain are adjusting. Give yourself permission to not be perfect. The more rows you work, the more consistent everything will become.
My free 5-day C2C email series will help you through the technique one step at a time with each new lesson. Each day you’ll receive a link to the next lesson designed to build your confidence and help the method finally make sense. By the end of it, you will have a 4″ C2C square. You will also learn a little bit about color changes. In the final day, you will make a small project.
If you haven’t done Part 1-C2C Crochet for Beginners, where we start our triangle, please find it below or sign up for the complete C2C Confidence Series, which will include 5 emails and 5 blog posts to learn beginning C2C. Once you have your beginning triangle made, find the increasing lesson below.
C2C Crochet Increase-Day 2
If you haven’t already done so, be sure to go to the Day 1 session from above to make the first 3 rows(blocks), which begin to form your triangle. Keep things simple and manageable for today’s lesson. Your goal is to continue increasing the triangle you’ve already begun. We will increase for two more rows, creating 5 blocks(as you know from the first lesson, I call them bumps) up and 5 blocks across, which is two sides of your 4″ square.
Abbreviations Used US Terms
ch = chain
ch 3-sp = chain 3 space
dc = double crochet
sl st = slip stitch
This is a continuation from Day 1 where you finished Step 4-the 3rd block (bump) of your triangle.

Step 5 {Increase}:
Make sure you turned at the end of last bump:
Ch 6, dc in 4th ch from hook, dc in next 2 ch
Sl st in the ch-3 sp, ch 3, 3 dc in the ch 3 sp,
Sl st in the next ch-3 sp, ch 3, 3 dc in the ch-3 sp,
Sl st in the next ch-3 sp, ch 3, 3 dc in the ch-3 sp, {4 “bumps” made} Turn you work.
Step 6 {Final Increase}:
Ch 6, dc in 4th ch from hook, dc in next 2 ch
Sl st in the ch-3 sp, ch 3, 3 dc in the ch 3 sp,
Sl st in the next ch-3 sp, ch 3, 3 dc in the ch-3 sp,
Sl st in the next ch-3 sp, ch 3, 3 dc in the ch-3 sp,
Sl st in the next ch-3 sp, ch 3, 3 dc in the ch-3 sp {5th bump made}, turn your work
Your triangle shape has now become bigger. Watch the complete 2 step video below.

A Small Win Worth Celebrating
As your triangle grows, take a moment to appreciate it.
You started with a single block…and now you’re building something that actually looks like a project. That’s a big step.
If you’re following along with the series, this is the perfect time to celebrate your progress — even something as simple as saying: “I made a triangle.”
Because that triangle means you’re learning.
Coming Next: Turning Your Triangle Into a Square
So until now, you focused on growing your triangle by increasing by 1 block (bump) each row. But in the next series, everything shifts.
You’ll learn how to stop increasing and start decreasing, which is what transforms your triangle into a square. This is the moment where C2C really starts to click for most crocheters. And once you understand it, the entire technique feels much more intuitive.
You’re building confidence one row at a time… and you’re doing better than you think.
