Our wedding is in late September 2016. About half of our 55 guests are out-of-towners, so we want to send StD (ideally magnets) before the holidays. We have already booked our ceremony / reception / main lodging.
Is there any reason NOT to send StDs already? I see that 6 months is standard but if we have the date set, why wouldn't we give our guests as much time to save / plan / think about it as possible?
