Granny Weatherwax on my car

Soooo.. I have this big scratch on the side of my car (clumsy me) that's just a straight line. I bought special markers to draw something over it but was lacking inspiration... untill I started reading the Wyrd Sisters by sir Terry Pratchett again :-) Granny: you're gonna hitch a ride with me!

(This is just the design, I will post the picture of the end result as soon as I muster up the courage to start drawing on my car)
