A primer on pockets. I want to know all the different kinds and how to knit each.

A primer on collars. Preferrably ones that can easily be integrated into Top-Down Knitting, but I am not adverse to Pick Up And Knit collars…


Also know any YouTube videos (or blog posts) on either of the above?  List them in the comments!  (Yes I’m lazy, but I never think of these things at home!)
