how to work back and forth
Hi, I'm working on a sweater vest, and I had a question about using a circular needle. The pattern says:
DO NOT JOIN, Neck Ribbing will be worked back and forth.
How do you knit on circ needles and NOT join? I found similar questions on the forum that describe how you use the needles as though they were regular straight needles, but for some reason, I still can't figure this out! Can anyone provide a clear and explicit description of how to work back and forth and not join yarn when using a circular needle? Thanks so much!
