Looking for new shades...
In addition to the new shade route, there is also the possibility of getting a little creative with the process. Assuming that the original roller tube and spring are still in good condition and functional, it would be possible to create fabric shades with a fabric of your choice seamed along the edges and glued to the roller tube at the top - - it might be necessary to adapt a slightly heavier bottom hem device than the typical wood insert to keep the shade pulled against the window. I don't know whether it is still made, but about three years ago you could find a special kind of window shade material that allowed you to iron-on virtually any fabric as an interior decoration element - - the advantage being that it was sold as a no-sew project - - the side and bottom hems were wrapped around the edges of the special shade material and ironed in-place as well. There are several in the Vintage Airstream Club who have taken one of these avenues to have "custom" shades for their coaches.
