Very versatile surface
"Mat board is a fantastic surface to work on. It is very sturdy and holds up to a lot of use and handling. Mat board handles acrylic paint, watercolor paint, ink and other media very well and can be used for many techniques. Make an notebook or journal using mat board for the covers, or various 3-D projects, or use it as a base for a wall-hanging. Die cut shapes from mat board to make your own embellishments or words. Cover the mat board with paper or stamp, ink or paint directly on the surface."
