Same style here.....boarding pass STDs, passport invites and postcard thank you cards. Our wedding is Nov 18th 2011 and I just sent out my STDs exactly 1 year in advance. Invites will be sent out in May which will give people 6 months to plan, save and schedule time off work. The RSVP date will be the end of August which will give me almost 3 months to finalize everything. Since a majority of things, such as OOT bags, number of tables, linens and napkins needed, number of favors, number of centerpieces needed and much more, depends on the number of ppl coming I want to make sure I know plenty of time in advance how many are coming.
