Found these adhesive clouds at Bed Bath and Beyond. Now they greet anyone entering the FaN. They look really cute from the ouside at night too - when the interior lights are on. They also work well on the inside walls. (I think I better not buy another package or else they'll be everywhere!)
As soon as it stops raining, I'm going to lift up the rear dinette window and affix some from the inside. If you come upon an Airstream flying down the highway with those clouds bouncing around on the rear window, you'll know who it is!
