Help With Increase on a Sleeve Pattern
I need help on a pattern for a bolero jacket please. This is my first foray into clothes and so far am enjoying the challenge but need help understanding this part of the pattern. I'm on the sleeves and have so far worked 2x2 rib and changed needles to work 2 rows st st.
The pattern then says "working in st st inc 1 st at each end of 3rd and every foll 2nd row"
Now, first of all, does this mean as I have already knitted 2 rows st st that my next row will be the 3rd or do I start counting from zero?
Secondly, I am reading it that I will increase at the beginning AND end of every 2nd row - is this right? That would make sense as it is a sleeve but just need some clarification!
Many thanks in advance!
