Your wedding invitations are one of the most important aspects of your special day. The invitation is responsible for letting your guests know the place, time and direction of your wedding ceremony and reception. Additionally, it sets the expectations of your guests, creates the mood, and gives your guests the first impression of what your wedding will be like.
If there are 180 total guests being invited, then the couple may only need 100 to 140 invitations. Always order a few extra invitations in case the couple realizes they forgot to add someone to the list. Also order extra envelopes in case mistakes are made when addressing the invites.
