Whoah! This is Hard!
I started sewing the bordered diamond blocks together, having never (that I can remember) worked with diagonal rows before, I've quickly realized that this is hard! What I mean is the side diamonds. I flip the triangle over to the adjoining block where I think it should go and sew it, flip it back and it's not where it should be. Well, I guess by the time I've finished it I will hopefully be an expert, if not I'll probably never do one again! I think if there weren't narrow borders around these blocks it would be easier to figure out. Looked online to see if there were any tip videos, couldn't find any, mostly stuff about navel piercing! UGH!!
