What is a what if Kit?
Its what I call my Emergency Kit or what if it all go's to hell!
Mini sawing kit and white thread, I have actually had to saw a bride into her dress, I wont tell :)
A cleaning kit to remove marks from dresses, and a lot more.
It is good to put your own kit together to you dont know when you might need a spare groom :).
Worth thinking about and planning for what could go wrong and then it either won't or you are prepared for it!
