You may say these stones doesnt have artistic value; I say these stones are perfect!
Think about leaving the number stones in the wild. Who find those will find themselves in mystery. And what about the 'Happy', 'We can do better', and all the other one/few word versions? They will do all the effects of a kindness rock can imgaine to do when found by strangers, them not knowing where these came from. I love them 🥳
