i think picking up stitches would be easier than undoing your bind off. there’s a video for picking up stitches here just as long as you pick up the same amount you had originally it should work great.
That is true. it may look a little odd picking up stitches and continuing from a bound off edge. You could also put your needle in a destination row and undo a row or two. there’s a video on that on this site too!
