Do you doodle when you are on the phone? I do if I’m on my phone. Its funny what comes into my mind. Mainly faces, patterns, thoughts.
These were drawn in biro on an old envelope. Sometimes I use italic pens or metallic ones. I tend to fill up all the space. I don’t remember when I did these. A few years ago?
And why not draw doodles? The more you practice art the better you can get. It also helps understanding what you are doing. I talk to myself sometimes as I draw to work out where I want to place features on a face for example.
