I've been Googling fun ideas for L's Mario birthday party, and have found some great ones, which I'll be sharing over the coming months.
One of the ideas I saw came a great party post at Giver's Log. The idea was to make a "pinata," minus the paper mache, out of a cardboard box. It's decorated to look like bricks, which the party guests can then punch, a la Mario, instead of whack with a stick.
I made my version out of a huge Cheerios box. With a ruler, about a dollar's worth of acrylic paint, and a yardstick, I was able to make a passable block of bricks.
It will be filled with plastic coins, Mario fruit snacks from Target, and Mario gummis I found at Dollar Tree.
Fun, super easy, and it cost about a buck.
