I would not use white permanent marker to try to mask the marks if the drenching with rubbing alcohol doesn't work. Without seeing a pic of the mishap to determine how large the mark and where it is located in the quilt it is hard to offer alternative ideas. But I would lean towards fabric paint before I would a white marker. The yellow will probably bleed right through the white and still show.
