I decided to replace my 'snowing' oem day night shade with a Bali cordless 'up/down' shade from Home Depot. Easy install after removing the valence. I will add some sponge since it swings a bit when up. Looks very good. 40 minute job with appropriate screwdrivers.
Looks good, and you can get some ventilation along with privacy!
Very nice and thanks for the pictures. I now see the solution to the mini blind which has been working on driving me insane with its endless thumping.
