The whole window will have a one foot wide window sill. I will have to show you the place to get a good idea of things. Basil planted in teacups for the kitchen, cheap and pretty teacups planted with fresh herbs on the window sill.
Love the interior of this restaurant called Bistro Charlotte (located in Warsaw & Cracow). They were inspired by the French cafes and hand-make all their own breads, baguettes in the age-old French style.
