Almost a year of planning... and I think I've finally found a book that would have really helped from the start.
Law Pack - Wedding Planning
http://www.lawpack.co.uk/cohabitation/product839.asp
I haven't read through it completely yet, but from what I've read so far, it's a very clear and non-bias form of Wedding Planning.
It reminds you of all the important things, like send out your invitations by this date and pick your flowers and colour theme, but also the legal side of the Wedding.
We were at a complete loss as to what to do, and I spent ages trawling lots of different sites to compile a complete list of what needed doing, and I'm still paranoid that I've forgotten something. This guide seems to have settle those fears.
I plan to go through it this week and tick off what I've already done.
GOOD LUCK TO ALL FELLOW WEDDING PLANNERS - I HOPE THIS RECOMMENDATION HELPS.
