How to get permanent marker out of fabrics
Buy a stain remover and read its directions.
Lay the fabric face down on a pad of paper towels.
This will protect the surface underneath and absorb some of the marker as you go.

Options are:
[A]. For some, this work may take a day or two. Other times, lightly mist the fabric with water for a minute or two..
[B]. Apply the stain spot remover to the underside of the stain. This pushes it out through the top surface instead of causing it to work further into the fabric..

The answer is:
[B].
