The girls wanted to make a mermaid pinata at first. Unfortunately Mermaid Pinatas do not fall under the catagory of "simple crafts." Besides that, who would want to swing a bat at a mermaid? It didn't take me long to talk them out of that.
The fish will do.
Cost: I'm not sure how to figure in the three to four cups of flour, but the water was free, the newspaper was free, I used craft paints I already had, so the pinata was FREE. The pinatas at the store cost $15.00-$20.00.
