An article organizer includes three interconnected panels which are foldable relative to each other from a flat position to an assembled position. One panel is a base panel that attaches to the window frame of an airline cabin window. A second panel is a support panel that extends outwardly from the base panel, transversely thereto and has opening into which articles may be placed. The third panel is a brace panel that extends at an angle to the base and support panels and which gives the organizer an overall triangular shape. Openings in the brace panel create support edges that engage the bottoms of articles placed in the support panel openings.
