Knit with circular needles, this cowl does not need any seam.
It can be wear with the I-Cord to be tighter at the neck or simply like a tube on the shoulders and the arms.
It’s an easy pattern to follow : all you need to know is to knit and purl. In the pattern, you can read the instructions to knit the I-Cord. You will need dpn needles to knit it.
In the description, I wrote 630 yards, it’s 3 balls of Patons but you dot used all of the third ball. You could knit a longer cowl.
Have fun to knit this cowl !
