We have one of these and someone put a piece of a popsicle stick and wrote "Rock Concert" - Love Rock Art.Garden Trinkets - Awesome Ideas, Projects and Tutorials! Including, from 'instructables', this creative 'garden thing' project with rocks.
I used a Lions Paw and 25 Clam Shells, sprayed with a clear finish for shine. The tinkler hangs, from top of hemp hanger to bottom of longest strand They make such sweet sounds moving in the wind. I call them ‘’tinklers’’.
