The pole really turned out nice.
And I love the towel rack. It is ideas like that, which can make all the difference in finishing a project, and making it special.
The doors look great too. You definitely have woodworking skills!
The solid copper would bring continuity to the whole project. Yet, the perforated metal seems more practical for the application.
I personally would lean toward painting the first perf. metal and see how it looks.
One thing that is definite, it has to tie into the copper theme somehow.
