Description: First we sawed the Ribba-picture ledge in three pieces: 25 centimeters from each side. The remaining piece, from the middle, went to garbage bin.
We put the picture ledge pieces against each side of the wall shelf. Then we drilled two holes to each sides, so we get holes to the shelf too. We cut the necks of the screw anchors away and hammered the anchors in to the holes in the shelf. Next we screwed the picture ledge pieces to the shelf. Now we have a nice computer stand. Your keyboard and mouse can be put under the computer stand and then you have more space in your table!
