This year my nieces requested a Spongebob Squarepants pinata. The challenge is to make the rectangular shape using paper maiche. If you use cardboard as a base for the pinata, it may well be too difficult to break, especially amongst pre-kindergarten age kids.
Step 1: Flat Sheet Paper Maiche
The trick is to make reasonably flat sheets of paper maiche from which to form Spongebob's body. The overall dimensions I'm making are 12"X16"X4" for the body. The top and bottom will be cardboard for stability and for connecting the sheets together; it won't prevent the main body from being broken.
First, I prep the support I will be using to build up the sheets. I am using a piece of plywood, laminated with formica top, with a generous amount of vaseline smeared all over. The vaseline will be key in getting the sheets off the top.
Prep the newspaper. I like to cut in consistent size squares, about 2" for this project.
