My goodness I am literally obsessed with todays style inspiration!
At present I am actually in the process of arranging the invitations for my own wedding, and i am obsessed with gold foiling stationary, a beautiful example can be seen below:
The process of printing this type of stationary involves using intricate laser cut gold foil that is then pressed onto the main card of the stationary.
I love the floral prints on this set of stationary and it shows how a simple colour palette of white, grey and gold works so well and you can see how minimal palettes are able to produce such a high-class look.
But a warning must come with this inspiration - you must get this done by a wedding professional and foiling does not come cheap, so remember to put aside some extra budget if you do want to achieve this look.
So to add that extra little bit of class to your wedding stationary consider gold foiling - you're bound to get the seal of approval from your guests!
