Rock painting is such a peaceful activity. Following on from my fairies, I decided to paint some wishing rocks, to go into a fairy garden. These are simple to do. All you need are:
Clear nail varnish
A tool to create dots - a skewer works well; you could also used a chopstick for larger dots, and toothpicks for small dots.
Gather some stones. I collected some stones from the beach, but I also bought a bag of rocks from the local dollar store. Give them a coat of paint, top and bottom and allow to dry. (Don't paint both the top and the bottom at once. Paint the tops and let them dry; then turn them over and paint the bottoms and allow to dry). It is easier to paint a whole pile at once rather than just doing one stone.
Dip your tool into the paint, and dot onto your stone. You can do whatever patterns you choose. I did a couple of random patterns, wavy patterns, and some circle patterns. I used one colour at a time, putting silver on all my stones; then chose another colour paint to put on and applied it to all my stones; and so on. This gives stones a chance to dry and saves you switching back and forth between colours.
When dry, apply a coat of clear nail polish to protect your stones.
