I have one of those mantles that has a big 'ol tv above it (not very pretty). It seemed like a good idea when we were building the house, but ever since I have always wished I had a mantel that I could properly decorate. And by properly decorate I mean put stuff there and not have my husband be annoyed because something is blocking the remote receiver.
But piano tops make good mantles too.
I actually have big plans to make my piano awesome, but for Halloween having it all old looking kinda adds to the effect.
I have a tutorial for the pumpkins here.
