Another FAB invite is The Wedding Tea Towel. Not only will guests have all the details of your big day, it's practical too. They also create save the date towels, so if you want to send these out the year (or maybe even longer!) before your wedding it's a great way for people to keep hold of and not lose the information until they get their new calendars!
Which is all totally true! Get in touch now for more info - firstname.lastname@example.org
