There's a lot to be said for long engagements, especially when planning a wedding can be much more than just a six or twelve month affair. Organise-Us has 16-month diaries from September 2009 to January 2011 in a range of gorgeous colours. There are also handy sections for financial planning (read: keeping track of your wedding spending), and a storage pocket for cards and receipts. The diaries are available at for £34.95.
