What a gorgeous sweater and I want to make it!
I'm not an expert knitter but I can follow a pattern. In Bolivia pattern there is armhole steeks. Can you please tell me what are steeks? I have never seen that term before.
A steek is cutting your knitting for a zipper or sleeves. You do this by sewing along both sides of the place you are going to cut so your knitting doesn't unravel. It was frequently used in the past for fair isle knitting in the round so that the knitter could knit the pattern uninterrupted.
