Knitting Technique: Long Tail Cast On

This is the cast on that my mother taught me, but I always forget how to get it started.  Is it over or under or how do I get that first loop started?!?! Come to think of it, I think we did the slip-knot to get things started.

Anyway, this video is really great and goes through it very neatly, and you don’t even need the slipknot to get started!
