Suggestions on when you should order your invitations and how many. Be sure to have confirmed details of your ceremony and reception before ordering your invitations. Please make sure you have the correct time, date and location of both the ceremony and the venue location. Have an accurate head count. Order one invitation for each single adult, couple, or family invited. Always order an extra 25 just in case you forgot someone or you may also need extra for wedding pictures. If you don’t order extra now and need more later on you will have to pay extra money by going back to the original price. Whereas if you order the extra 25 when ordering your invitations, you will only have to pay a few dollars more.
