I love an open kitchen. My dream kitchen would have glass panels on all cabinets, for two reasons: one) it's a terrific way to force oneself to think, "inside out", that the inside should be as pretty as the outside. And two) there is something so welcoming and joyful to me about the idea of walking into a kitchen where you can see all of the lovely things one uses to serve the people they love!
And what you can't see down below should be equally as calming to view when one needs to get something. Just as lovely as it is when someone tells you, "You are as beautiful on the inside as you are on the outside."- So should be your kitchen.
