I like the little day bed and the window and beat board walls. day bed on plywood base with built in table. we would put the long edge further back for under the bed storage space. I also would want to paint it like white or something.
This bright yellow window-frame provides such a vibrant pop of colour, the whole room will feel put together and complete! This would go especially nicely in a simple, all white room with a few other matching yellow accents-stunning! BR x
