By all means a "champagne problem", but half of the time I try to operate roll-up blinds, I get the blinds moving in the wrong direction. The cord is completely outside of the blinds, and it can easily twist, so I can't tell which of the two sides at the bight of the cord to pull.
What mechanisms for opening and closing blinds eliminate this guesswork?
It's just statistics after all
