This is a great variation on painting, to give your children a different experience.
Step 1: Gather some old/new toothbrushes. If you get old ones, make sure you wash them first! Get some colour paint, paper, and colour pencils for details (if you want).
Step 2: Use the toothbrush as your paintbrush to make some shapes.
Step 3: Use the colour pencils to finish more details.
Step 4: Use your imagination, have some fun!\
