Stuck on neckband- how to pick up stitches?

Hi all I really need some help I have only a few weeks to finish sleeveless pull over and I’m stuck on the neckband!
Never had to pick up stitches before, can anyone direct me to a utube video maybe, so I can understand what is required

Sometimes I use a crochet hook. I almost always use a smaller needle because my picked up stitches tend to be too loose. HTH
