Wallflats embossed wall tiles remind me of plaster mouldings in a clean modern aesthetic. The tiles are made of paper. You can cut them to size and install them yourself…
Their adhesive backs are removeable (but not reuseable) for when you move, so they’re perfect for spiffing up a rented apartment.
The white-on-white texture of the tiles looks like traditional tin reliefs or plaster wall panels, but in sharp braile or check patterns.
