I love KH!!!

So far all of the help I've needed has come from Amy's superb videos but now I need help with
this pattern. First how do I do a do a 2-Stranded cast on? It explains it on in the pattern but I must be stupid because I can't follow the instructions or the diagram. Is it like the long-tail cast on? I hope cuz I'm really good at that now after watching Amy's vid like a million times. It's a good thing the vid is digital and not a tape cuz I would have worn it out as many times as I've played and replayed it. Okay I'm done rambling now. Thanks in advance.
