Шаль вяжется в две нити.
The shawl is worked with two strands of yarn held together.

Update: There’s a new pdf available now. The major change compared to the previous version is that in the next RS rows yarn overs (YO) are now knitted through the back loop (ktbl), rather than just knit, which in my opinion, makes the YO look more rounded and neat. The updated version also provides more detailed information on provisional cast on method, charts and symbols. However, the previous version pdf is still available.
