In this modern world we are all busy people - seriously, in order to organise a get together with close friends I often have to plan 2-3 months in advance, especially in the popular holiday months. With this in mind, you may want to consider “Saving The Date” with your guests early on in your wedding preparations. After all the last thing you want is friends being unable to make your big day because they have unknowingly double-booked themselves!
Some people use email, text message or even Facebook to save the date with their guests and whilst these are an easy hassle-free option they may not be ideal - I'm sure I'm not the only one guilty of failing to remember something important in a text I've read or accepting a Facebook event invite only to forget to put the event in my diary. A physical save the date is a much better way of making your guests aware of when your big day is.
