If my pattern says to end on a WS, do I work that wrong side, or do I end when I get to it? I question it because it seems redundant when previous instructions say to work 10 sets of 12 rows, which would mean working that last Wrong side.
Not sure if it matters, but the next step is to do a 3 needle bind-off. I’ll be scouring the net for videos for that too! 
Thanks! THis forum is so helpful!
Usually when a pattern says to end with a WS row it means to end with the WS row [I]completed[/I]. And yes, that would be redundant when they’ve told you work a certain number of rows. I would just make sure you complete the number or rows indicated.
Also, there is a video here ( you’ll have to scroll down to the bottom of the page … I believe it’s the last video on the page) on KH on how to do a three-needle bind off … it’s super easy to follow! 
yes, do the last WS row, so you turn the needle around and are read to knit the next row.
There is a 3-needle bind off vid right here, near the bottom of this page:
