Sunburn Art is a Real Thing, and It's Glorious
This lady is going to find out soon enough that those lines create a pattern that leads to some historical treasure. I can see it now, "National Treasure 3: Sunscreen Art Map" starring Nicholas Cage. It might not do well in the box office overall, but it'll make a killing in the sunscreen art fan demographic.
If you're trying to get a custom sunburn then this type of blanket is simply the best way to to go. She chose to go for an abstract design, but surely anything can be stenciled if you've got cloth and some scissors. Who knew that UV rays and art would mesh so well together?
Judging by his body language it seems like this young fellow is none too thrilled with this design. He was shooting for a more current, less tribal look, but got this instead. Worry not, friend, it doesn't look so bad from certain angles...maybe.
