Hi! I’m new to fairy gardens and want to make one for my daughter! I’d like it to be outside and might want it in a big planting pot. What kind of things can I fill it with? I have fake moss, but if I were to keep it outside, can that stuff get wet?

I also saw some ideas about styrofoam for filling and then the last few inches using little rocks. Would that be ok for being outside and getting rained on? Idk if styrofoam can get wet over and over again, I’m inexperienced. Thanks!
