Hello
I don’t have a fav video but I like to slip the stitches which are on hold onto a spare needle, a smaller needle than the one I’m knitting with as I’m not comfortable kniting off a holder.
I look at how many stitches need picking up in each section and decide where I’m going to do those before I begin so that I pick up relatively evenly and if there are a lot to pick up I might place a marker or two in the section to remind me I need to pick up so many before the marker and so many after. And I like to focus a stitch each side of the shoulder, or 1 right in the central shoulder to bridge any gap which could be there.
I sometimes put a life line of embroidery thread in the held stitches before starting and that way, if I don’t like the pick up, or the size of the finished neck, it is easier to rip it out and know my live stitches are safe.
I saw a video once where the tip was to pick up in every stitch around the neck and reduce the number to the correct stitch count on the next row. This gave a nice pick up on one particular neckband I made but I later decided it wasn’t always suitable, even so it was a good tip, now if I feel I need an extra stitch on the pick up to close a gap or look neat I feel confident to do so and then work 2 together in that place on the next row. It can prevent holes and gaps nicely.
I’m sure other people will have their own tips and tricks too.
