This is the worst book I have come across. Advises you to cut corners even on things like hair and makeup (which will be in photos forever) massive fail as far as I'm concerned. Every other tip is a little vague. Just think that the person who wrote this thought that they were on the pigs back by writing a book with Wedding in the title and thought that was a sure way to cash in. Ive got a wedding tip for saving money.... Don't waste money on this book!
I would say The DIY Wedding Manual is aimed at someone that does not have a creative bone in their body. A lot of the ideas are ridiculously basic and annoyingly simple, and also things that I have already thought of or researched on the internet. There are also lots of typos in the book.
Unless you are a complete uncreative novice that has never planned anything in your life, I'd save your money and use the internet where you are also provided with pretty pictures.
