Though parts of the world are beginning to open back up, travel is still something we’re all doing from the comfort of our armchairs right now (and besides, I am firmly in camp #StayHome for those of us who can, to help others who can’t). So lately I’ve been remembering one of my all-time favorite sketchbook subjects: doors, gates, and courtyards. And this drawing seems to sum up all three.

What I love about drawing a door, other than its own inherent aesthetic qualities, is the fact that it represents a question: what’s on the other side? Long ago I lived in Rome, a city chock full of hidden courtyards and walled gardens—though I spent a whole year wandering (and sketching) every street and back alley, I only ever got to see a fraction of what lay inside the doors that faced the street. It felt like there was a whole separate city behind those doors, and every time I was afforded a glimpse of it, I was thrilled. I’ve felt the same feeling in a few places here in the States—namely Santa Fe and New Orleans—and when I sketched the above drawing, that feeling hit me with full force again. I’ll probably never get to see the inside of this little walled garden, but that doesn’t matter: with the orange trees and bougainvillea spilling over the stucco, it’s enough to imagine the little world that lies on the other side of the door.
