If there's a particular reading during the ceremony that is special to both of you, print it on the program for your guests to take with them. The wedding program can double as a party favor. You might even include a note to your guests on the back of the program that thanks them for coming. If you've gone to the trouble of selecting special materials for stationery items, consider carrying the look through to the guest book. Custom stationery stores offer tools and grommet rings to reinforce bindings and hold a book together.
Many papers also come with matching card stock to use for front and back covers.
Invitations always need to be sent or delivered four to six weeks before the wedding. Plan thank-you notes to coordinate with everything else. If you get stuck on wording, consult an etiquette book or go to a stationery store to check sample invitations. A quotation, love poem or song lyrics send a unique message about your wedding and your feelings for each other. Consider having your specially created invitations hand-delivered.
