Key storage- door at the end of a kitchen cabinet for small storage. This gave me the idea that the inside of a cabinet door should be painted with chaulkboard paint so you can keep notes or grocery list there.
Hidden cork board for recipes, shopping lists, etc. More ways to hide the messy stuff - I love it! Can do more than one cupboard this way. Another idea: paint the inside of a cabinet door with chalkboard paint for grocery list, or pantry contents.
