I’ve realised something recently… I use i-cord edges a lot.

In fact, in my latest design I’ve added them to the armholes, neckline and side slits—and I didn’t even think twice about it. It just felt like the right finish.

And I think that’s the thing with i-cord. Once you start using it, it quietly becomes one of your go-to techniques.

So what is it about i-cord?

For me, it’s all about the finish.

It gives you that lovely, neat, rounded edge that just behaves. No flaring, no messy edges, no wondering if it needs “something else”—it already looks complete.

I especially love it on:

• necklines (it frames them beautifully)
• armholes (adds structure without bulk)
• shawls and scarves (hello, polished edges!)
• and even side slits, where it gives a really professional touch

It’s one of those small details that makes a big difference.

A quick bit of knitting history

If you’ve ever wondered about the name—i-cord was popularised by Elizabeth Zimmermann, who apparently called it “idiot cord” because it was so simple.

Which feels about right… until you try it for the first time and think, wait… why am I not turning my work?!

If i-cord hasn’t quite clicked yet…

You are absolutely not alone.

This is one of those techniques that often makes more sense when you see it rather than read it. And sometimes it takes watching it a couple of different ways before it really clicks.

Here are a couple of really good tutorials I recommend:

• A clear walkthrough of both the cast-on and bind-off:

• A slower, step-by-step i-cord bind-off:

• And if you like having options, this page has a few short variations:

Have a watch with your knitting in hand—it makes all the difference.

Patterns that use i-cord (if you want to try it out)

If you fancy giving it a go, here are a few lovely patterns where i-cord really shines:

• Sophie Scarf – simple, relaxing, and all about that neat edge
• Dotted Rays – a great example of an i-cord bind-off in action
• Age of Brass and Steam – a classic shawl with a beautiful finish and it's FREE!

They’re all great for seeing how i-cord works in a real project (and not just in isolation!).

And in my own designs…

 I’ve used i-cord edging in quite a few of my patterns over time, but four that really highlight it are:

• Confluence Scarf - every edge is an icord edge
• Damica Shawl  - finishes off with an icord cast off.
• Brioche Headband - 1 stitch icord edging - FREE pattern
• Delphic Wrap - simple icord edges.

And of course, my newest design (which I can’t fully show you yet 👀) uses i-cord on the armholes, neckline and side slits—which gives it that really clean, tailored feel.

I’ll pop another sneak peek below so you can see what I mean…

Final thoughts

I-cord is one of those techniques that doesn’t shout for attention—but once you notice it, you start seeing it everywhere.

And more importantly… you start using it everywhere too.

If you’ve never tried it, this might be your sign. And if you already use it—tell me, where do you love adding i-cord most?
