A bare bottom is often considered comic gold. Many Halloween costumes incorporate them, so much so that plastic fake bottoms are often sold in costume shops. If you want a fake butt without paying high prices, you can make your own out of papier-mâché. This simple craft uses newspaper and glue to build shapes. With a bit of painting and sewing, you can incorporate a big old bottom into your costume.
Place side by side two sports balls that are the proper side for the butt you want to create. Kickballs or basketballs will likely be the best option.
Duct tape the two balls together to keep them in place. This will create a form to work on.
Cover the form tightly with cling film.
Tear newspaper into 10 cm (4-inch) squares.
Mix equal parts of water and white glue in a bowl.
Dip the newspaper squares one by one into the glue mixture, then smooth them onto the form.
Completely cover the form with newspaper.
Build up at least five layers of newspaper. You can use more if you want the bare bottom to be extra strong. Apply additional layers around the edge if you plan to sew the bottom into a costume.
Allow the bottom to dry.
Remove the bottom from the form and trim off any rough edges with a sharp pair of scissors.
Paint the bottoms with several coats of flesh-coloured paint. If desired, paint on comic details such as pimples or a heart tattoo.
Sew the fake bottom into your costume with strong thread.
