There should be a “wedding planning confessions” site. Here’s my contribution about invitations: even though all the books say you should write out the complete address with no abbreviations, I simply refused to write out the state names. Except for a couple of the short ones. I didn’t even use the old style medium length abbreviations (which you can see on this chart). I used the common two letter postal codes. It’s a good thing I’m not inviting Miss Manners or the President.
