Paper mache is a crafting technique that involves using paper and a binding agent, usually glue or flour mixed with water, to create three-dimensional objects. The paper is torn or cut into strips and then layered over a mold or framework. Once dry, the result is a lightweight and sturdy structure. This method is popular for making decorative items, masks, and sculptures. It is often used in art projects and school activities because it is inexpensive and easy to work with. Paper mache can be painted or decorated after drying, allowing for creative expression.
