I painted two of these is less than 30 minutes, so it's really a quick (and did I mention inexpensive?!) project! They make great teacher gifts, hostess gifts or a treat for yourself!
Have fun creating!! (Note: The best place to use these are under a covered porch,where the weather won't further deteriorate them. I may try and spray an acrylic coat on top to see if that extends their life a bit.)
