Please help

Hey guys

I am stuck on a pattern and was hoping for some help. The pattern is for a romper suit and I am about to shape the right armhole, here is the pattern

k15, turn and complete this side first for right front.

I have no idea what they mean by that.

Please help

You’re going to work on one side of the front first. When the pattern says “turn”, it means to switch the needles in your hands, just as you would at the end of a row. Leave the other sts unworked and you’ll get back to them later.
