are there any good videos that describe how to pick-up stitches from the neck or any edge?

Many thanks indeed -

There’s a video on picking up sts on the Tips page. Basically, you pretend your edge is the left needle, insert the R needle into a stitch on the edge, wrap the yarn around it and pull through. You’ve just ‘picked up and knit’ the first st. Usually on the back of the neck you pick up one st in every st on the edge; on the sides of the neck you’d pick up about 2 sts for every 3 on the edge. That would be - pick up 2, skip a stitch, pick up 2, skip 1, and so on.

Here’s a helpful tutorial for picking sts around the neck, too.
