Thankyous In Ceremony Programs How Long Did It Take You To Send Out Your Wedding Thankyous?

How long did it take you to send out your wedding thankyous? - thankyous in ceremony programs

We are very disorganized, and even had problems sending invites all the time! I'm afraid it's getting late and we still have half of the left to write thankyou notes! Some say you have to send one years, others say 3 months or less! How long did it take?
