How to Crochet a Granny Triangle

How to crochet a granny triangle.

Let’s take a look at how to crochet a granny triangle. Below is a very speedy pattern that I’ve recently used for a crochet granny square sweater. You will also find my video tutorial for these granny triangles on YouTube.

When & How to Use a Crochet Granny Triangles.

Granny Triangles are useful for slotting between granny squares, allowing you to create crochet projects on the diagonal. By which I mean, rather than having lots of granny squares in rows, they’re placed in a diamond formation. To square things off, granny triangles fit neatly between the rotated squares.

Granny triangles would be great in crochet bunting, too. Or, make four large triangles and join them together for an interesting twist on a granny square blanket!

Anyway, I have put together a video tutorial, demonstrating how I crochet these cute little granny triangles. I recently used the triangles in a new granny square jumper. The jumper (sweater) is currently drying on blocking mats, and I hope to show it off soon!

Now that my new jumper is finished, I’m thinking of potential new projects. Imagine a colourful granny square blanket edged with triangles! I do not need a new blanket, I do not need a new blanket….

The colourful, harlequin image above (the one with the ribbing being knitted) is this biased/diamond construction. You’ll see the row of triangles just underneath the ribbing. This granny triangle is the pattern used in that crochet jumper.

Things You Need to Crochet a Granny Triangle

This is a quick pattern and blog post today, so I won’t ramble on unnecessarily. I used double knitting yarn (DK) and a 4mm crochet hook. This is a stash buster, so gather your yarn scraps for this kind of project.

Another useful thing you might need? The crochet pattern for the petal centre granny square matching the following granny triangle pattern.

For ease and brevity, I am just using US terms here; note that a US dc (double crochet) is a UK tr (treble) stitch.
You can substitute the initial chains and sl st with an adjustable ring (magic circle).
When changing colour (every row), a Standing Start is a great alternative to a chain 3. Take a look at the matching granny square video tutorial from 05:12. It’s my fave, but you can keep to chains at the beginning of rows if you prefer.
Note that the dc2tog creates what I refer to as a “petal” in the video tutorial.

To begin, chain 4 (I accidentally ch5 in the vid tutorial, but I forgive myself, it’s OK), join with a sl st to create a ring.
Row 1: Ch4 (counts as 1 dc and 1ch here & throughout), into ring work *dc2tog, 2ch: rep from * 2 more times, dc2tog, ch1, 1dc, fasten off and cut yarn, do not turn. — 4 “petals” plus 1 st at each end.

Row 2: Ch4 [or 1SSt and ch1], 3dc in first 1ch-sp, 3dc in next 2ch-sp, (3dc, ch2, 3dc) in centre 2ch-sp, 3dc in next 2ch-sp, (3dc, ch1, 1dc) in last 1ch- sp, do not turn. Fasten off and cut yarn. — 3 granny clusters per side plus 1 st at each end. An increase of 1 granny cluster per side is made for each following row.

Rows 3 & 4: Ch4 [or 1SSt and ch1], 3dc in first 1ch-sp, *3dc in next 2ch-sp; rep from * to centre sp, (3dc, ch2, 3dc) in centre 2ch-sp, rep * to last 1ch-sp, (3dc, ch1, 1dc) in last 1ch-sp, do not turn. Fasten off and cut yarn.

Sew in ends. When it comes to joining granny triangles in a fancy new crochet project, they’re easier to manage with sewn-in ends. Trust me when I say it’s a colourful mess of uncontrollable spaghetti if you don’t!
