Use only Bristle Brush, no undos. This doesn't mean you don't make mistakes, only that you keep painting to fix them. This can give an organic quality to your work as paint adds to paint.
* Use only the Procedural Bristle Brush to paint.
* No undos (on occasion, one or two may creep in).
* One entry per artist.
* No image loads, make it all in SketchClub.
* Any subject you want. References are okay. If you use a reference, please credit your original source.
