A while back I wrote about my problem with cordless blinds. You have to reach up to grab the bottom of the blind with your hands to pull it down. My daughter is 5' 1" tall and can't reach that high. So I have now developed a means of operating them for short people.
My first action was to attach simple key rings, the kind you get when you buy a new lock, to the bottom of the blinds with cable ties. Then I screwed some hooks into the end of a couple of dowels. Now all she has to do is reach up with the hooks and pull down the blind until she can reach it.
Raising the blind is a different story. The hooks don't work for that. So I found a scrap of wood about 3/4" square, probably something I ripped off of a piece of 1" lumber. I cut it to a reasonable length, with an angle cut. Then I attached a clothes hanger to it with the open end facing the angle cut at about 3 inches from the end. Now she can slide the end up behind the blind and catch the bottom of the blind in the clothes hanger and push it up. Opening the blind isn't quite as simple as opening it, the blind tends to sag and try to fall out of the hook of the clothes hanger, but it is relatively easy to do it.
So now it is possible for a a short person to open and close the cordless blind.
