Use the straps and roll up the back window. The side windows I sandwich together, then fold the rear seat up a bit and place the windows on the back of the rear seat. Then I fold the top back, folding in the two rigid side/rear/corner pieces onto the top. After the top is back, fold the rear seat back into its upright position. This keeps the two side curtains in place and against the rear seat. Once you do it, you will see why i do this.
