We're redoing our teeny tiny half bathroom, and I'm thinking about stenciling one or two of the walls to add some interest in there. It's only 25 square feet, and I'm wondering if I do a stencil if I should do two opposing walls or just do one wall?

The layout is - one wall has the toilet and sink on it, across from that is the only full wall, to the left is a wall with a window, and to the right is a wall with the door.
