Hello, we are forming a U-shape with our cabinets. Now we have to cover the back of the cabinets. I have an idea where someone used wood to cover the cabinet back. (http://www.ikeahackers.net/2014/09/making-a-pax-room-in-the-living-room.html) However, to use the same idea (but with dark wood to have more modern look) Every hardware store has told me "it can not be done" or it is very expensive at 450 €. I did not want to pay more than 200 eur. The back is 200 cm wide and 236 cm high. I want something unique, not just hainging curtains. If you have any ideas, please share! Thank you!
