Zentangled Papier Mache Skull

I purchased a papier mache skull from Beverly's Crafts, painted it with white Gesso like I did with the Zentangled Box and drew Zentangles with a sharpie paint pen, dip pen and sharpie markers. The paint pen and dip pen works the best on an items primed with gesso. The sharpie markers don't work as well once you use them on a surface painted with gesso paint.
