This is a series of pictures we took while repairing our shades a few years ago. I thought I would post them in the hopes that it would help other people understand how they are put together and can be repaired.
I am convinced that a lot of shade problems are the result of too much tension on the cords. My suggestion is to apply only the minimum tension required to make the shades stay in the up position.
