South Pole is a hat that features Estonian traditional
knitting technique called “vits”.
The pattern includes photo tutorial, a full video tutorial from cast-on to finishing and in depth video tutorial about tubular cast-on.

Tubular cast on technique is used for
casting on to give professional look as well as a nice
stretchy brim. However, you can choose a cast-on technique of your choice.
After creating the tubular cast on, the hat is knitted in
round. An elastic thread is inserted into the brim to keep
the rib nice and stretchy.

YARN
The pattern is created for both yarns, SMC Highland Alpaca and DROPS Polaris. I recommend SMC yarn as it is softer and drapes better.

The hat will use up entire two skeins of yarn, so you will need to unravel the swatch (no need to buy expencive yarn for swatch).

NEEDLES

US17 (12 mm) circular (or size to obtain gauge).
The length of the circular needles depends on the
method you prefer for a small diameter circular knitting.
When you choose a magic loop technique, take circulars
at least 40” (100 cm) long. When not using the magic
loop technique, take 16” (40 cm) cirular needles.

NOTIONS
Yarn needle, few yards of contrasting colour thick cotton
yarn for cast on, crochet hook, elastic thread, knitting
marker.
