Wouldn't this be a cute wall hanging for the nursery?
For the invitations, I am toying with the idea of doing a boxed invitation using Kraft jewelry boxes and a bed of 3D butterflies like the ones above...?
DIY Butterfly mobile to mimic this Pottery Barn Kids one:
The mobile could not only work to adorn the party space, but also to decorate the nursery.
These would be cute centerpieces because they add height and they are natural as well as simple. Guests could take a pot home for their prize when playing shower games.
