How To Paint a Child's Face Like Spiderman?

When my son was small, I would use liquid eyeliner to paint a spider web pattern on his face. You can do it quite cheaply with makeup from the dollar store.

I would start by dividing his face into four parts drawing a line down the center and across the bridge of his nose; then paint additional lines evenly between the four quadrants. I would join them up by painting some 'u'-shapes between the lines and voila...a Spider-man face. I never actually needed to bother with a red base, he was happy with the spider web alone.
