I wanted to share with you this amazing idea that I found over at Junk Market Style. I'm working on my own version.
These springs are new versions of the old bed springs. They're not quite the same dimensions so maybe that's why they don't sit the same. I doubled them to make the wreath more substantial. There were purchased on ebay.
So, here is my version. More of an oval wreath, but pretty similar. It shows up much better on a white door.
