This was a simple project. Before I assembled a new $20 fan, I spray painted the fan body and the stand green, the fan blades light yellow, the fan cage a darker yellow, and the center medallion brown. Using paint left over from other projects, this turned out to be very inexpensive. And, since the fan started out disassembled, I didn't ever have to take it apart to begin!
Before I began painting, I first wiped each part with paint thinner to make sure I was starting with a clean surface. Then, I simply painted each piece. I actually thought about adding artificial leaves to the stand, but decided against it.
I've painted a number of these white fans over the years, but this is the first time I painted one to look like a sunflower. I guess its a matter of taste, but I like it much better than the boring industrial white!
