Aircon Scarf

Aircon scarf : an easy knitted scarf free pattern

This aircon scarf is a simple summer free knit scarf pattern with a twist: some simple lace sections are added to this simple garter stitch scarf. Don’t panic, these lace sections are very easy and beginner-friendly.

This simple, yet elegant design combined with the cotton yarn is exactly what you need to fight the aircon during the summer. On top of that, it goes with any outfit. I always have mine in my handbag just in case.

No time right now, pin this free knit scarf pattern for later.

The yarn I choose for this summer scarf pattern is LionBrand 24/7 cotton yarn. It’s a nice and sturdy worsted weight cotton yarn. It’s very comfortable and easy to work with. I absolutely love the charcoal color (check out the Sunshine Crop Sweater which uses the same yarn if you’re not convinced yet).

Scroll down for the free version but I recommend you purchase the ad-free PDF Pattern to get all the instructions and pictures in a nice PDF you can print and take notes on without relying on your phone or an internet connection, I’ve got you covered!

The Aircon scarf is now available in my Ravelry and Etsy shops. Add it to your cart now before you forget.

Before you Start


  • 6 mm knitting needles. I’m using this basic set of double pointed needles I love in the step by step pictures but you don’t need them. You can use straight needles or circular needles if you prefer.
  • Lion Brand 24/7 cotton yarn. You need 2 100g skeins ( 340 m / 372 yards) in charcoal color.
  • Tapestry needle to weave in the ends. I love this set as it has different eye sizes for different yarn thickness and it comes in a small tube which is very convenient so I don’t lose them.
  • T pins for blocking.


  • k =knit
  • st = stitch
  • k2tog = knit 2 stitches together
  • yo = yarn over = bring your yarn forward

Repeat the stitches between * * the indicated number of times or until the end of the row.

Repeat rows between ** ** the indicated number of times.
