I'm helping a friend of mine figure out what to use as a wedding card box and it's amazing to see how creative people can get in planning for their wedding card boxes. Here are some interesting ideas.
A vintage mailbox
Old fashioned suitcases for a travel themed wedding
A pumpkin carriage money box for a Cinderella themed wedding
A wooden breadbox, for a tropical themed wedding
or something cool, like this =)
or pretty like this...
and of course, birdcages are pretty popular
Can be used as centerpieces too, like this!
or a cool homemade dollhouse, like this.
