2. Cardboard Frames That Look High End

Cardboard is one of the cheapest materials available, yet when cut and layered correctly, it can mimic the look of real wood or expensive store bought frames. To start, cut two identical rectangles of cardboard for each artwork. One forms the base while the other forms the frame border.

You can layer thin strips of cardboard to create depth and visual interest. Wrap the board in kraft paper, burlap, fabric, or contact paper that resembles wood grain. Another option is painting the cardboard with chalk paint, acrylic paint, or spray paint. Add a matte varnish for durability.
