ornate gas heaters..........

i don't have any pictures. but could some of you use your imagination and come up with something for me to do with some old gas heaters i have. i would like to use them outside with candles in some way. all i can tell you is that they are designed ornately with metal up the sides and on the front. and the tops are a grey/brown ceramic. they are all different but are about the same size. i have 4 but don't have to use them all. this has to be a first but i really like these old things and any ideas would be appreciated. thanks. barb
