I have settled for the "Cosmic" display system and specifically sheets divided into two pockets. The top pocket is large enough to take most covers and cards. For an outsize item I can use a single pocket page.
Since none of my material is shiny white FDC stuff, I wanted to avoid white paper for my write up which would just make my postal history look grubby. (It is grubby but let's not emphasise that). I wanted to use grey paper but that has to be ordered each time - you can't just pick it up at your nearest copier paper shop. So I am using cream as a second choice.
The write up is done in grey brown rather than black (which from a computer printer is too stark) and I use larger font sizes, 18 for headings and 14 for text. I try to vary the text and not to spend time on the Obvious - so I don't in general describe the stamps (which anyone can just see ..) unless they have some notable feature.
This is what it all now looks like:
