Crochet Shell Stitch

One thing that I love about this infinity scarf pattern is that it’s made using the shell stitch. I think shell stitches are so pretty and they create such a lovely fabric.

The best part is that there’s a variety of different shell stitches. I used the full shell stitch for this pattern, but for my shell stitch baby blanket pattern, I used the open shell stitch.

So it’s pretty neat to see how you can crochet this stitch in so many ways.

How to crochet an infinity scarf?

For this crochet pattern, you will first start by making a long crochet scarf using the shell stitch.

Then you will put the two edges of the scarf on top of each other and seam them together using the whipstitch method.

That’s it. At this point, all you have to do is work in any remaining ends.

So it’s a pretty basic pattern. Perfect for beginners!

What type of yarn do I need to make this scarf?

For this pattern, you’ll need about 500 yards of worsted weight yarn. I actually used a yarn that I found at my local second-hand shop.

I personally couldn’t believe that I found it, it was 4 perfectly intact skeins of natural wool and cotton yarn. Have you ever found yarn at the thrift store?

So the yarn that I used for this pattern is Yarns Brunswick Berber Tweed in the color Birch Bark. It’s a wool/cotton mix with thick and thin strands of yarn.

Since I found this yarn at a second-hand shop and it seems to be discontinued, I can’t recommend it. So here are some other options I found online that you can use.

Or you can use any other worsted weight yarn that you have on hand.
