We're using Mandalay Wedding stationery for our invitations, place cards and thank you cards (and maybe menus, not sure yet!). They're huge in the UK, are in all the wedding magazines and have won a number of awards and we love their stuff.

These are the proofs of our invitations and RSVPs which we love, they're pretty and are perfect for our wedding.

They also do these great co-ordinating photo albums and guestbooks which are lovely.
