Plates in the garden

Hi,
My fence is chain link. I have lots of shade, so I thought that I could put some bright plates on the fence above my flowers to brighten up the areas. So I picked up some beauties at Goodwill. Now I need to figure out how to secure them to the fence. Anyone ever done this? My DH suggested using epoxy glue to affix wire to the back of the plates and hang them from the wire.

Thanks for any suggestions.
