The stitch used for this piece is called "Trinity Stitch" or "Bramble Stitch". I did modify the original stitch pattern a bit: instead of (k1, p1, k1) in the same stitch, I will have you do (k1, yo, k1) in the same stitch. I found this a bit easier and the result is the same.
I have been obsessed with this stitch... So much that I needed to see how it knits up with all different kinds of yarns and needles.
It's so much fun to do this stitch and I couldn't stop trying more and more!
You can make a scarf or make your scarf into an infinity by sewing the ends together.
So far, I have been making this stitch in the following yarns and needles:
