Weaving in ends

I just watched some you tube videos about weaving in ends. I understand the process, except they don’t explain what to do with the tail left from the cast on and the tail left from the bind off. Can anyone direct me to some good you tube videos or give me some good advice which would be very appreciated.

This video shows a way of weaving in the end left from the bind off (about at 3:00min).

You can weave in these ends in a manner similar to other ends or you can use the edge created by the cast on or bind off. There’s really no set way to do this.
