How many favors to get?

All the weddings I have been to usually there is one favor per couple. So maybe if you tally up the number of couples and single guests, that would give you a good number to start with.. then maybe get some extra just in case??? I'm going to see what other girls say as I am not sure myself!

The amount of favors should equal the amount of invitations sent. WHich basically is what the person above said.
