Blue Leather

Blue Leather
my son has inspired my cream leather sofa with a blue pen, how I can remove it??

my 6yr old has been based on my couch cream leather in blue ink and proving very difficult to remove, when I was done not to worry about removing that as I thought it would be a problem, does anyone have any idea, I've tried almost everything.

Have you tried a q-tip with alcohol in it?
