Ariana Page Russell has dermatographia, a skin disorder that causes her to welt up with even just a little scratch. Fortunately, despite how they look, the inflammations are painless.

The welts only last about 30 minutes, so she has a limited amount of time to scratch out some words or design and then photograph it before her work is gone and she’s back to normal…
