Sometimes all you need is a little curtain.
Something short and sweet.
Like when there’s a banquette or window seat underneath the window.
Or in a bathroom, where you don’t want long drapery panels to get wet on the floor.
Or when there’s big heavy moulding around the window and you want to see it, not cover it up.
Or when you want a cottage/cafe-style look.
Or when you just want to keep it short and sweet and in the window.
In most situations like this we would use a shade, like a Roman shade or a woven wood.
But sometimes you may prefer the softness of a curtain, so you can see the whole, verticality, of the window/view when the curtain is open.
When a shade is open or pulled up, the window is top-heavy. All the color and pattern and softness are at the top of the window, even hiding a bit of the outdoors from your view (not that there’s anything wrong with that, it’s just that in some situations this might not be your ideal treatment).
So, sometimes, in certain situations, short curtains are just right.
