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.
DIY Berry Picker: This berry picker is made out of PVC pipe. Heat is used to shape the plastic. Two "fingers" at the working end do the picking. The berry then falls through the pipe and lands in a plastic bag tied to the other end.
