Just because you have a drop ceiling doesn't mean you can't decorate your space with hanging plants. I found a great product that fits right on the track between the ceiling tiles and holds my plants beautifully.I just try and keep them spaced out so there isn't too much load in one place on the ceiling supports.
After I discovered these handy hangers for my plants, I realized that there were many more uses for these little boogers. I used one to hang a rotating mobile over my baby's crib. Several went into my son's room to hang his model airplanes and helicopters that he had made. One went in the office to display a sign pointing visitors the right way.
Went I went to open house at the kids' school, I noticed in one classroom, the teacher had used them to display the holiday crafts for Easter that the kids made.
As you can see, there are plenty of ideas out there for using plant hangers for a drop ceiling in many different ways. Why not share your most clever use for a ceiling hook?
