Thanks, everyone, and great suggestions for improvements. It was kind of a whim of the moment and I just went with what we had on hand. So far, it is holding up OK. The Elmer's is still holding up, although it may well degrade by the end of the season. My chickens have also scratched at it and flung pennies here and there, but again, not too bad. As expected, the surrounding plants have mostly hidden it now, but the slug damage to the ligularia is noticeably less than usual.. This is my test necklace, and I think I will make more permanent rings for next season, using water proof glue and perhaps one of the suggested alternate bases (although cardboard is plentiful and free).
