What if the cigarette end burns a hole in the carpet?

Cut the burnt part along the edge, as round as possible, and cut it to the bottom.

Don't be afraid, go to the corner of the carpet against the wall and cut out a similar "circle"

Make up and fill in. It is usually difficult to see that this is a supplement.

You can pick the hair at the junction, it is difficult to see that the mixed hair has been mended!
