MDF (Medium-density Fiberboard) is made from recycled wood fibers, glued together under high pressure. It is strong, dense, and a great choice for folk art painting and many crafts.

Medium Density Fibreboard (MDF) is a reconstituted wood panel product. It is a dry-processed fibreboard manufactured from wood fibres, as opposed to veneers or particles, and is denser than plywood and particleboard. MDF has an even density throughout and is smooth on both sides.
