The Yarn For An Infinity Scarf

This scarf design may seem intimidating at first, but I can promise you it is not hard to get the hang of and can be made in less than 2 hours! Let’s discuss the yarn you’ll want to get to make this infinity scarf before you get started.

You will need a little more than two skeins of this color, so you will need to know all about changing yarn colors in crochet. It is easy, so be sure to check out the tutorial I linked up for it and take a look at the video tutorial too.

This scarf design is worked up with Wool-Ease Thick & Quick in Sea Glass. The Sea Glass is one of my new favorite colorways of Thick & Quick to date (close behind is the Hudson Bay color!) and has such a beautiful mixture of colors.

According to Lion Brand, the color of this yarn is Ice Blue mixed with Bark Brown, Navy Blue, Jade Green and Oatmeal.

Wool-Ease Thick & Quick it is a great yarn for winter patterns like scarves (or infinity scarves like this one), hats and more! It is considered a super bulky six yarn, which means that you’ll be able to work up a project fairly quickly and start another, which is always a good thing when crocheting.

Tip: I used less than 2 skeins of this yarn for my infinity scarf, but if you’d like to buy one extra skein to account for differences in crocheting (crocheting tight or crocheting loosely) then it is a good idea.

You will want to try to get approximately 72″ per row, which is about a little over a half an inch per stitch.

Hometown Usa Yarn Lion Brand

If you are allergic to wool, a good substitution would be Lion Brand Hometown USA yarn, which is 100% acrylic. The Hometown USA line has a sizeable variety of colors available to pick from, so you can still have the chunky infinity scarf look that this pattern was created around.

I also wanted to mention that there is a Thick & Quick yarn that Lion Brand has that has ZERO wool that would also work well in this scarf design and is also an exact match as a substitute. With either yarn choice, the infinity scarf will turn out as intended!

    1. Hi Darci,

      I’d start with the same starting chain but join with a slip stitch to the first chain to form a circle. After that I’d chain 1 and work the pattern as written but join each round at the end with a slip stitch and a ch 1.

      Hope that helps!


  1. Hi! I was wondering what crochet hook size you need. I clicked the link for the hook you had but it was 0.9 mm instead of the 9 mm you said we would need. I am pretty sure 0.9 mm would be too small for a weight 6 yarn but I just wanted to make sure before I purchase the correct hook.

  2. I just started this! It will be the first wearable I’ve ever made! I plan on gifting it to a co-worker for Christmas Thank you!
