I’m a big fan of shared google docs and this is pretty good! All-in-One Wedding Planner thanks to Style Me Pretty and Google. Because it's based around an American wedding we did spend a bit of time customising sections but, if you've just started your wedding planning adventure and need a bit of help I think this is a really great starting point. The tips at the bottom of each tab also got us thinking about what elements of a traditional wedding were important to us.
All the best for your wedding planning!
