Cut two of the 4-foot-long 1x1 garden stakes so they are each 34 inches long. Attach one of the 4-foot garden stakes to each end of a 34-inch 1x1 with the 2-inch wood screws to form the top of the frame. Measure down 30 inches from the bottom of the 1x1 and place a mark. Line up the top of the edge of another 1x1 with the mark, and attach with 2-inch wood screws to form the bottom of the frame. Repeat to make a second frame.
In a well-ventilated area (or outside), spray the frames with your choice of spray paint, letting dry between coats.
