My Friends and I

I saw this today and thought it was a cute ideal. The second picture shows how she put the plate on a platic pipe (I think that's what it is) and attached that to the wall. Maybe glued??? I'm sure if any of you want to do this you could come up with some way to make it work. Let us know if you do this project and how you did it.
The plates here are cute, but I would like vintage ones instead.
