Materials: 5 white Lack-shelves 30*26cm
Description: The walls in my bedroom are so bad, single shelves wouldn't stick to them. So I put two and a half together to shelves with two levels. Now each is put to the wall on four points and the upper and lower ones are reinforcing each other. And I even have more space on the shelves.
Its done really easy: buy five Lack-shelves (three if you only want one table). Have one cut in half and glue together two complete and one half shelf in a u-shape. Drill wholes in the right positions into your wall and attach the shelves. Ready.
