(Hope my grammar is OK I'm from Mexico, and English is not my native language, I did my best to write this instructable so If you do not understand something or notice very bad grammar, please let me know to correct it)
The challenge of this instructable is to make a pinata recycling paper, so you don't have to spend money to make it (maybe you will need some crepe paper to decorate it and a balloon but it cost less than $10)
Step 1: Materials
Old newspapers (the quantity of newspaper will depend of the size of your pinata)
For decorating your pinata maybe you will need old carton boxes, brilliant papers, etc (use your imagination)
An assistant (is optional you can do it for yourself, but if you have children at house they'd love to help you, for this example, my 5 years old niece was my assistant)
