A little practice drawing on the iPad.
The resolution of the piece you create is rather low when you send it to your computer, plus the app I’m using, mostly PhotoPad, requires that every time you want to change color, erase, change pen width, whatever, you must go to tools, brush, choose from a number of options and then go back to your drawing, so flow is interrupted.
But then, after a while, you get into a new kind of flow, doing what you have to do.
And there are advantages–when you erase, you completely erase. And when you save an image, you can then draw and erase on top of it without touching the saved portion. It’s kind of like layers, only not as good.
