Paper is normally made from wood pulp. Wood is ground up and mixed with water and other chemicals to make a thin liquid called "paper pulp". Paper pulp can be bleached to make blank paper, and dyes can be added to make colored paper. This pulp is pressed into sheets of paper. When the sheets are dry, they are cut into pieces of paper.
Sometimes paper is made glossy (shiny) by adding clay or other materials. Sometimes paper is made from other kinds of paper. This is an example of recycling.
Not all paper is made from wood. Other kinds of fiber can be used also. People make paper from cotton, linen, and hemp.
