I love this idea. Unframed prints inside a hung window frame create a kind of shabby chic shadow box that's very personal and also easy to update anytime.
Although this isn't exactly a potting bench, it does a nice job of showing what warm rustic style a weathered table can bring to a room. A potting bench in a living or dining room will add both function and personality. I'm a big fan of adding furniture and decorations throughout the cooler months and taking them away once spring arrives — warm and cozy in the winter, cool and fresh in the summer.
