There isn’t much difference between elopement announcements and wedding announcements. The biggest difference would be mentioning location. Couples often elope to a fun destination and want to share where they were married on their elopement announcements. If the couple eloped to the local county courthouse, they might choose to forego mentioning location and just use wording that celebrates the marriage on wedding announcements.
You can order discount wedding invitations and change the wording to reflect an elopement and/or announcement. Our friends at Invitations by Dawn have some great wording ideas for both. Read Elopement Announcement Wording and Wedding Announcement Wording.
