Since I know nothing about planning a wedding, I'm taking a lot of hints from this infographic I found on Pinterest.
We also have a physical wedding binder for all the important hard-copy documents, keepsakes etc. The key in all of these thing is that they're accessible to others, and easy to keep up. I share my Pinterest board with my Matron of Honour, and the Google Drive and binder with Ian.
We also share a Google Calendar to note wedding-related appointments - and, of course, everything is colour coded the same!
To give you an idea of where we're at: in the 3 weeks we've been engaged, we already have a date (next November), we have appointments booked for venue viewing and commissioner meetings and already have a decent budget laid out. I've also asked my part of the bridal party to be involved.
What are some things you used to keep organized when planning your wedding?
