How do I remove pencill drawing from carpet?

[cocopops]

On xmas eve, DD drew a large hexagon on our wool carpet in pencil. Have tried a rubber and also white vinegar which usually removes stains from this carpet but its still really visible. Any ideas?

That should say PENCIL!

Vanish upholstery and carpet foam and a scrubbing brush and get your dd to do it

thanks- always a bit worried about vanish as its made marks in previous carpets when I used it....
