How do you repair a cigarette burn from a car ceiling?

Find a spot of the lining that is hidden (ie: under a piece of plastic trim) and cut out a small square that is just larger than the piece that is burnt. Cut it out with a very sharp Exacto Knife (or similar) and then cut out the same size and shape around the ciggie burn. You then use a good glue to stick the good square into location whre the burnt square was and chuck away the burnt spot.
