Directions for Adult Surprise Jacket

I am having great trouble with the directions in The Opinionated Knitter for the Adult Surprise Jacket. They don't make much sense. I can't figure out where you on the sweater body you start the knitting from. I also find the diagram, with multiple points marked with the same letter, quite confusing. Has anyone redone these directions so that they are easier to use? If so, could you tell me where I might find clearer directions.

This is a cute jacket but hard to knit from the original directions.

Thanks,
Diane
