How can I get the look of concrete walls?

Interiors

Exposed concrete seems to be very popular right now. How can get the look without actually having concrete walls?

Some use drywall texture or knock down patterns to give a rough feel. Plaster and wire are another way to create custom finishes on walls and ceilings.
Another easier way is wallpaper.
Rubbed Concrete Mural Wallpaper M9232 - sample as found on Houzz.
Good luck! Hope this helps
