Step 1
Mix equal parts flour and water until the mixture is the consistency of glue. Dip newspaper strips into the mixture one piece at a time, pulling each strip gently between your fingers to remove excess. Wrap strips around the inflated balloon until the balloon is completely covered except for a 1-inch area around the knot of the balloon. Allow to dry overnight.
Step 2
When it is dry, pop the balloon and draw it out through the opening you've left. Paint the balloon shape yellow and allow it to dry.
Step 3
When the paint is dry, fill the shape with small wrapped candies or trinkets. Wrap string around it as if you were tying a package. Make sure the opening is at the top and leave a long piece of string for hanging your piñata. Make an X-shaped cut at the bottom of the piñata to make it easier to break.
Step 4
From the black construction paper, cut a circle about 4 to 5 inches in diameter. From the yellow construction paper, cut sunflower petals.
Step 5
Glue the construction paper petals around the circle to create a sunflower. When it's dry, glue the flower to the sides of the piñata.
Step 6
At the party, let kids try to break the piñata with a small baseball bat or a decorated piñata stick (available at party stores). Put a grown-up in charge of making sure all the children are well out of the way of the swinging bat!
