These remind me of mandalas. We could get stones and do mandala zendoodle art on them, and then write a simple encouraging message on the back for baby girl. Make a nice fabric bag for her to keep them in.
painted rocks - love this house! This would be an amazing idea to do with children or even secretly for them and hide the rocks in the garden! I would have been taken to a whole other world of imagination if I found fairy houses in our garden!
