Thank you! There is no written pattern for the cowl, it's my freestyling. However, it's very easy to make.
It is basicaly a turtleneck that gets wider with one row of increases.
Make a swatch of 3x2 ribbing over 20 stitches and measure it. Decide how many stitches you need for a comfortable fit. I think I had around 110 st but it was too scrunchy and was choking me gently, so I had to block it over a round object to make it a bit larger.
Cast on a desired number of stitches with a German or any other stretchy cast on. Proceed in k3p2 pattern for a desired length. (I was using 16' circular needles and then put it to 36' circulars for fiting process).
When you reach desired length for the neck, start increasing. Add one M1 between 2 purl stitches. (Pick up yarn between the stitches and purl through back loop). Proceed in 3x3 ribbing until you get bored, cast off loosely. That's it
(By the way, the hat is made holding thread double for the chunky look)
