Paper maché

Papier-mâché (UK /ˌpæpi.eɪ ˈmæʃeɪ/, US /ˌpeɪpər məˈʃeɪ/; French: [papje mɑʃe], literally "chewed paper") is a composite material consisting of paper pieces or pulp, sometimes reinforced with textiles, bound with an adhesive, such as glue, starch, or wallpaper paste.

Two main methods are used to prepare papier-mâché; one makes use of paper strips glued together with adhesive, and the other uses paper pulp obtained by soaking or boiling paper to which glue is then added.

With the first method, a form for support is needed on which to glue the paper strips. With the second method, it is possible to shape the pulp directly inside the desired form. In both methods, reinforcements with wire, chicken wire, lightweight shapes, balloons or textiles may be needed.
