Definitely take a look at the video for picking up stitches, if this is something you're unfamiliar with. Look here
about 3/4 way down the page.
As far as your instructions for the body. I would say that it should go like this:
Row1: Knit across all stitches, then before turning work around (so needle with all stitches is still in your right hand) pick up 10 stitches. Turn work around.
Row 2: Knit across all stitches (the first 10 being the ones you just picked up) and at the end of this row, pick up 10 more stitches.
This would bring you to the 116 stitches that are required.
Does this help??
