Doing Mattress Stitch

My project is different than most because the rib runs horizontally not vertical so when the video show picking up the two lines inbetween the V’s it doesn’t really apply for me because there aren’t any V’s? Can you assisst with doing the mattress stitch in this case please? Thanks, Laurie
