I love this cowl and decided to make one for myself.
The simplicity is the key here!

I also made a translation into Russian language on my blog here.

Мне нравится эта нашейная бандана своей простотой.
Я сделала перевод на русский язык для тех, кого она заинтересует. Вот здесь.

I am making it with acrylic yarn, since my friend is allergic to wool.
Needles #10.5
Have to knit pretty tight.
After short rows I switched needles to #10 / 6mm
Did a very loose bind-off. It looks too loose.
Next time I will use “Surprisingly Stretchy Bind-off” method.
Hope blocking will help.

Cowl is blocking.

O! I love this cowl! Have to make one for myself!

Notes - changing needle sizes helped me to achieve better fit around the neck.
Bind-off will be better in Surprisingly Stretchy Bind-off. I used this Cat B video.
Cast-On better be loose, so it doesn’t pull at your chest.
Wrap & Turn didn’t work well for me. I had to do the yarn-over instead - it keeps my knitting from puckering.
Knitting it with wool would make for a huge difference and better blocking.

Re-done the loose Bind-Off after the pictures of Bandana were taken.
It looks and fits much better now.
