I’m involved in the Kindness Project, which involves decorating rocks/stones with encouraging or fun things and hiding them for others to find. Rocks can be decorated with transfers, paint, colored pencils, etc. Being that a lot of these are planted/hidden outdoors (and I live in Florida), what would be the best type of resin to cover them with? Resin-covered rocks are especially pretty, but soft resin-covered rocks – not so pleasant!
