Artistic room painting, how much?

hello, all -- i apologize for the probable stupidity of these Qs. first, i can't figure out which way the ceiling fan blades are supposed to go in winter and summer. the switch makes them turn clockwise or counterclockwise, of course, but i can't feel any difference in the air flow, so i'm not sure how to set them. second, when choosing clockwise or counterclockwise, am i supposed to look at the blades as if being below them and looking up or as if being above them and looking down? thanks much. -- susie margaret

I need to remove a stubbornly attached round ceiling medallion, 27" in diameter, that was above a chandelier on a drywall ceiling. It appears to be made of a sturdy lightweight material like plaster or hard foam. I would have assumed it was attached with adhesive, and it may partly be, but I'm pretty sure I have felt some inaccessible metal nails or screws when trying to pry a spatula up under it. My concern is that I am going to severely damage the drywall ceiling if I pull this down. It's a visible area in the center of the dining room and the ceiling has a very small/fine texture. :confused:
