What a great idea!
This envelope also has something very exciting inside.... I don't know what but it feels very bulky! :-)
I'm afraid I'm going to steal this idea too...:D
And I just noticed the wax seal - very impressive that it survived the trip from Australia.
Honestly you guys would LOVE this if you could see it in real life.. My photo does not do it justice - it's soooooo cool! And it's definitely got some thing cool inside... It's a very FAT envelope!
