How incredible are these invitations – made of very thin real wood they are then engraved with a personalised message.  This one in particular I liked with the tiny bird on a branch, and thought they would make lovely wedding invitations if you had the budget and wanted something really unusual and special.

They are made (I believe) in the Netherlands but can be shipped anywhere in the world, and new trees are planted when one is cut.  Take a look at their Etsy shop for more designs and details.
