We recently stayed with an older gentleman who lives alone. He loves to read and wanted to display his sports trophies, but his books were piling up and his trophies as displayed, were hard to dust. He consented for us to organize a little. The purpose was not to sell or stage, just to lighten the workload for him and make space for our visit.
A solution was to introduce shelves for his books, and also the trophies. Although a closed unit with glass doors would keep dust off, we used an open unit to make the books very accessible. He was pleased with the changes, and also that the shelves fit on top of his cabinet which he wanted to keep for extra storage.
