Start by making a frame out of toilet paper tubes. This will make a smallish piñata, so you might want to make several, if you are planning for a number of children.
Cover one side of the frame with paper strips dipped in watered down glue, about two parts glue to one part water, and allow to dry.
Flip the piñata over. Punch holes in the toilet paper tube sides for hanging strings, and ribbon accents (if you like).
Cover the rest of the piñata with glue dipped paper, leaving an opening for candy.
Once all of the paper is dry (this can take overnight), decorate with tissue paper, painting on strips with more watered down glue.
Allow the tissue paper to dry. Fill the piñata with candy. Glue the opening closed using a glue stick, or regular school glue.
Hang the filled piñata as a party decoration until it is time to break it open.
It's great to be a homeschooler.
