I'm very similar to Fred. Any writing I do in a notebook or pad isn't for anyone elses eyes so I don't fuss with it. What I *DO* do - and here's a nod to International Left-Handers Day today - is put something underneath the left side of a notebook so it is raised as high as the right side... until you are more than 1/2 way through. It helps me having an even writing surface.
As to actual correspondence, I use a clipboard with a couple sheets of paper affixed to it, and darker so I see the outline of my pages. This gives just a small bit of cushion but not too much. For being LH, I rotate the writing surface about 30 degrees or so to the right, but most importantly I have a pad that is about 1-2" high that I place under the top of the board, to put it on an angle. It seems like a big hassle but it's really nothing. Naturally, this is all when I write at home, anything out and about is catch as catch can.
I actually have a shot of the writing setup:
