Using corbels
If your breakfast island is on the more modern side, with no decoration, and you would like to make it a bit more interesting, you can with only a few items and a minimal amount of skill.
Mount the wood planks up the sides of your island, giving a little more depth to the flat surface. Then take some corbels and mount them under the edge of the counter. Paint everything the same color, or go more adventurous if you’d like, and you’re ready to breakfast in style!
