Finishing project

I am stuck on a pattern for a sweater vest it has a v-neck and don’t understand the pattern when it says right side facing, join yarn and bing off center 3 sts, K to end. Work 3 rows even. I am a beginner could someone please help me. :shrug: [color=darkblue][/color]

You are dividing for the front where the V starts, that’s why it tells you to ‘join yarn’ because you will need two balls from here on in, one for each side of the neckline. Does your pattern asks you to knit to the center 3 stitches and then join yarn and bind off center 3??? That would make the most sense. Then the ball of yarn that you’ve been using all along will remain for the front left of the sweater (as worn) and the ball that you are joining will be used for the front right of the sweater.
