There is definitely a technique to it. I find it easier to do it with the mirrors folded. First goes on pretty easy and second takes a little effort but if you get it aligned it will go relatively easy with a bit of a stretch before you go on or off.
Basic cover technique is to fold cover over in half, from front to rear or rear to front, so dirty touches dirty, then fold so clean touches clean. There is a natural fold point at the mirrors where you can work on them either as you are half way going on, or half way going off. Hope this makes sense.
