At my last calligraphy guild meeting, I saw an idea I absolutely loved. You bind a little book, but the pages are just "stubs". To each stub you attach a card or envelope, so you can flip through the cards like a book.
I have the instructions and making some books is on my "to do" list... Which means it might be quite some time before it actually gets done. But I will definitely post photos when it does!
oooh I like that! Thank you!
this website (or blog) has a pretty good tutorial for a book that is even easier to use as a base for a book of envelopes.

they have you fold your own accordion for the spine of the book which is fine if you like to fold paper
but
you can buy a Redi-Shade at Home Depot or Lowe's (for about $$5) and cut sections to use for the accordion fold.
Redi-Shades are temporary pleated shades to hang in windows until you get your permanent shades or curtains figured out.
There is enough paper in one Redi-Shade to make about 20 books.
Somewhere I have a tutorial - but it may take a while to find it.
The tutorial link I sent has a lot of extra embellishment.
It can be much simpler
and if you Google accordion books you will find other examples.
