Your invitations are the first impression guests get about your wedding, so take time to get it right. Look at sites selling invitations online and in magazines such as Wedding Ideas as they can provide inspiration. You will soon learn what you do and don't like.
Packaging And Embellishments: If you're adding embellishments, or you're mailing more than just an invite plus an RSVP card (we opted to mail more info, because of the destination aspect), keep track of the weight of your invitation suite once it's all packed up. Depending on its size, you may be facing more postage fees than a simple stamp will cover. You can get a postage estimate using a kitchen scale and checking on the USPS website. Through the USPS website I also learned that square invites and envelopes cost more in postage, by a significant amount. It's not worth it.
