Lay your hat upside down when setting it on a surface, rather than laying it down on its brim. This is important, since laying your hat on its brim could cause your hat to flatten or otherwise lose its shape.
Hang your hat on a hat hanger or place it in a hat box when storing it overnight or longer. This will help your hat to maintain its overall shape.
Grab your hat by the crown, not by the brim, when removing it from your head. This will help maintain the shape of the brim.
Avoid exposing your hat to high heat or humidity, as this could damage the felt fibers. For example, do not place your hat near a stove, heater or in a hot vehicle.
Remove dirt from your hat by brushing it with a hat brush designed for felt hats. Beginning on one side of the hat, brush the fabric in short, directional strokes, working toward the other side of the hat.
Tear off a small piece of masking tape and gently tap the sticky side against the surface of the hat. This will remove any remaining lint left by the hat brush.
Slightly dampen a clean cloth. Wipe the hat in short, directional strokes working from one side of the hat toward the other side. Allow the hat to dry completely before wearing it.
