Funny thing when I first glanced the topic, I thought it said, (how to take down a light pole.)LOL Sorry...
If the shade is the (V) blind type, there should be a button in the bottom at each end just where the string ends.
These bottom buttons (one on each end ) hold the string in that draws the blind up. you can pluck the buttons out with a flat blade screwdriver.
If you are referring to the top of these blinds, the cap at the end of each side slides out towards the inside, then the whole blind can be removed.
Its much easier to pull the blind up just past the half way point before you try to remove them. This way you don't have the full length swinging around as you pull it down.
I hope this helps, good luck
