Will you settle for a ready_made template? Or, will you create a specially_designed, customized wedding card? If you want to create something unique, then you must plan in advance _ at least 2ι months in advance. You can also consider ready_made wedding invitations templates, which are stocked by reputed wedding invitation printers. Will some wedding guests come from faraway places? If yes, send them a simple invite a couple of months in advance just to ensure that they do not make any plans around the time of your wedding. You can state in this plain Jane card that a formal wedding invitation will follow. Wedding invitations must include a booklet (that fits into a pocket) that lists a schedule of events. Such booklets help the guests know what's coming next at them. However, do not make this a very wordy affair _ you don't want the guest to keep flipping through the pages trying to find some find information while an important ceremony is going on.
Know what colors your wedding is themed around. This should not be a problem for brides but if the groom is taking on the task of ordering the invitations, he should definitely collaborate with the bride or the maid_of_honor to ensure no mistakes are made. It would be a travesty if the wedding colors are pink and mint green and the invitations are ordered as lime green and coral.
