Things you'll need:
Water
Flour
Balloons
Cut newspaper
Cupcake liners
Glue gun
Rope
Candy

Some cut newspaper works well for a piñata. No one will see it so don't stress over making it coordinated with your party theme.

Cover balloon one full layer at a time. Allow time to dry between layers (I did 10 layers) This is tedious but well worth it.
Once your final layer is dried you can pop your balloon. Cut a 3-sided trap door and drill a hole at the bottom. Fold the clothes line in half and knot the bottom. Pull top threw the drilled hole and out the top to hang.
Fill the piñata with candy. You can add additional layers over the trap door and secure around the rope or just duct tape it, which is what I did.

After folding both packs of cup cake liners in half I began gluing away (starting at the bottom and covering the knot) alternating colors.
