Many automobile sun visors are made of cardboard that is covered with a foam-backed fabric. You can easily repair most of these cardboard sun visors with a little foam-backed felt and glue. Fixing it yourself is easy, and worth a try before you go to the expense of buying a new sun visor.
Unscrew the sun visor and remove it from the roof of your car. Peel back the fabric carefully from the visor. Repair any breaks in the visor with packaging tape.
Place the headliner fabric on a flat surface with the foam side facing up. Open up the visor and place flat on the headliner fabric.
Trace the outline of the visor on the foam side of the fabric one inch larger than the visor all the way around. Cut the fabric along the outline.
Apply glue around the edges of the fabric and on the edges of the visor so that glue will touch when you fold the fabric over the edges of the visor. Let the glue sit according to the package directions.
Fold the fabric in over the edges of the visor. Clip the fabric in place with clothes pins until the glue is dry. Remove the clothes pins.
Apply glue along the edges of the folded fabric.
Reposition the mounting hardware. Fold the two sides of the visor together and press closed.
Secure with clothes pins until the glue is dry.
Mount the visor back in your car.
