I haven’t bought the video, but I don’t know that it can help you with what you are asking. That just takes practice. If you are unfamiliar with using either continental or english you can check this site at the basic techniques tab above and learn how it’s done.
I normally knit english carrying the yarn in my right hand, but for the two handed technique you use both so it is awkward especially at first. I find I can’t do purling very well in continental so I try to adapt by using my right hand for that stitch if it’s in a pattern.
After I did the sampler this was one of my first projects.
All said and done though I’m sure the video is very helpful and probably offers more hints and tricks.
