Here a few baby shower elements you can use with any baby shower theme!
How stinkin' adorable is this wreath?!? Use strips of any coordinating paper and add a pair of paper or real baby shoes! If you do paper ones, you could even embellish with an initial or glitter, etc! Source, shoe tutorial
A piece of fabric closed with a diaper pin is such an adorable touch you can use at any shower! Use different color pins and you can help people keep track of their drink too! ;o) Source
I LOVE a great topiary! This sock topiary is not only adorable, but helpful to the mom-to-be as well! Source no longer available :o(
A really sweet idea is to have everyone leave a special message for baby - cover a cork or foam board with coordinating fabric, make embellished cards and hang with thumbtacks. Source
