Why not search for a nice pebble out on your daily exercise and take it home to decorate! You can use your imagination to create different designs and use paint to make it super colourful. Maybe you could write a little message too, like thank you, stay safe, keep smiling, anything to make people happy.
You could leave them somewhere people walking past might see to make them smile!
