Thank you Audry. I thought about gluing them but I decided to wait until I put whatever plants in that I want there. I will need to pick plants hardy to Zone 4. I will probably pick these up and keep them inside over the winter. But you are correct about the wind, rain, and animals. I am on a ridge so we always have wind, very seldom a breeze. Thanks for your input. I hope to do more of these with different themes.
