Ok we're getting married in August and we're on a TINY budget so we plan to have a very small and intimate ceremony followed by a drop-in reception for everyone else. So what is the proper etiquette for invitations? We were thinking of just sending save the dates to the people we really want there and making a FB event for everyone else. I know it's our wedding and we can do it however we want but I'm still curious if maybe that plan is tacky or considered poor-mannered...
