Here's a window card that actually makes more sense than mine. Designer Mary Pelling's husband pointed out that if the window is opening toward you, you must be standing outside, not inside.
So...Mary put an indoor scene in her window. Don't you love the brickwork?
Best of all, she most graciously shared her svg file, which you can get here.
Here's another Christmas card by Julie Johnson.
