Go outside and collect a variety of smooth stones, wash them and them leave them to dry. Use a fine paintbrush and some acrylic paints to paint the stones with beautiful designs.
Stone painting has become an extremely popular hobby, so if you need a little inspiration, just pop online and see what other people have come up with.
Apply the paint to the stone one coat at a time until you have built up your design and then use a white paint pen to add dots.
If you managed to find any plain black stones, you can draw a design them just using a white paint pen. It looks fantastic, doesn't it!
