Fill a paper bag about half way with goodies (like candies and small toys).

Roll the top of the bag down, staple the folded top shut, and punch two holes along the top.

Cut strips of tissue paper and cut fringes in them.

Glue the fringes of tissue paper to the bag (glue along the top of the fringes). Cover the bag with tissue paper.

Decorate with paper cut-outs, markers, paint, and/or googly eyes.

Tie a long string through the holes. You will eventually hang the pinata up using this string.

Glue long crepe paper streamers from the bottom of the pinata.

You now have a scary monster pinata. Hang it up and break it open with a soft bat (like a Nerf bat or a tightly-rolled-up and taped newspaper).
