What I've been doing lately is German short rows. This is such an easy method and gives you nice smooth shaping with no holes. The poster did this backwards in my opinion. She started with teaching you the purl rows and went to the knitted row with her second video. It will probably make more sense to you to watch part 2 first and then part 1.
