Cotton paper is made from cotton fiber, as opposed to the traditional tree-based paper. The use of cotton fiber yields a softer, more flexible paper that is favored for its look and feel.
Cotton paper can also be recycled multiple times, making it a more sustainable option than traditional paper.
In addition to its environmental benefits, cotton paper has a number of aesthetic advantages. Printers often prefer it because the printing process creates less ghosting and results in sharper images.
