Maybe I should call you later and talk you through it!
I never work on ones with printed designs, so I always just fold the material like a greeting card and mark the approximate middle, then work out from there.
Another thing that I find makes it easier for me is that I use a highlighter to mark the stitches I've done on the pattern - that way I can still see them if I make a mistake somewhere, but it's easier to pick up again.
The fastening bit - I usually hold a bit of string back, and make sure it gets "wrapped" in the stitches on the underside. Does that make any sense?
