I spent the afternoon lunching with a friend in Santa Monica, and after we wandered through a huge, expensive (Santa Monica beach-side) antique mall. A creative find there that I love was this vintage button grapevine wreath. It would be easy to duplicate in a favorite color and would lend whimsy and femininity to your doorway.
What I thought was great about this wreath was that it wasn't hastily hot glued, but was carefully wire-wrapped, so it will withstand lots of usage without buttons falling off. This would be really easy to do with a grapevine wreath as opposed to a foam core. The gold wire used with the white buttons elevated its sense of formality. I also loved the big finishing bow at the top.
