I got in early today with my drawing of the paint brush. There are so many different shapes and sizes, so get one ore more out and give it a go. If you have a biro that is no longer working, don't throw it out. It is very useful for drawing fine hairs in before you draw them in with graphite. It indents the paper so that it leaves very fine subtle texture. I use it a lot in my drawings.
