Every once in a while, when I find myself with a desire to draw and no paper handy, I'll pull out the phone and open up the Procreate app. I love this app! Right now I only have the default brushes, but they are certainly enough to do some really interesting things. I did this sketch while on the plane over Christmas. I had forgotten to bring along my stylus, so I had to do this one with my fingers! It was a good way to keep myself busy for a little while.
One of the cool things about the app is that it also records the screen as you're painting, so you can keep the timelapse video of it. People seem to enjoy watching a painting come together from a blank canvas, so sometimes I'll post these videos to Instagram (@liz_hume).
I definitely need to work on learning how to create details with the app, because right now I still don't have a ton of control. But like with anything, practice makes perfect!
