You will need non-toxic fabric paint, a paintbrush, a pre-washed cotton shirt, and the foot, hands, thumbs, and fingers of your little one!
A washable, tiled floor is a great work area.
Have your child pick a color for the trunk of a tree. The sole of your child's foot will serve as the trunk, so paint it accordingly, and, with your help, have your child press his or her foot onto the shirt. When you do this, be sure to have the toes facing down, as they'll serve as the tree's roots.
Next, paint the inside of your little one's hands whatever color is decided, and have them press their hands, fingers spread out wide, on either side of the top of the tree. (If you want a fuller tree you can do this again.)
Pinkie fingers are great for blades of grass and flower stems. Tips of index fingers are great for flower petals. Thumbs are great for tree fruits. Be creative. Add sun, sky, birds, clouds, etc.
