My friend had a decorator come to her house to give her suggestions. They stopped at our house for a couple hours. One of the things we asked about was how to display some of Gerry's clock collection. She laid them out on the floor and then Gerry transferred them to the wall. He had to make a shelf for three, which he made out of steel and painted black so it would not be a focal point.
She also made the suggestion for the placement of the clock on the right. She certainly had an eye for this type of thing.
