Is all the information finalized? What things may still change?
Obviously the list can go on and on. The important thing to remember is that this is your event. Small details may alter some small elements of your invitation, but you must feel comfortable with the look and style and feel of your event as seen from the perspective of your invitations. If you are having trouble finding the right invitation, consult any of the invitation designers that have invitation collections closest to the styles that do appeal to you. Oftentimes, your invitation may be out there, you just may need a hand in scoping it out! Good invitation designers recognize the importance of finding the right invitation that suits you and your wedding or event. You should never feel pressured or intimidated into selecting an invitation that you are not fully comfortable with.
