Using a diagram

I’m pretty good at reading patterns but I’ve never tried just using a diagram. I got a book from the library and looked at some articles. Here’s the one I want to try and my biggest question is…where do I start? I can’t yet see a time #1 to indicate the starting point. Any help will be gratefully received.

I can work my way through the knitting pattern diagrams from the Japanese but this is something else. I wonder if the Ravelry group devoted to Japanese crochet patterns might be able to help?

Thank you! I’ll give it a try!
