I've been playing with different ways of sketching for this year's Inktober - drawing a small do-able something most days. I like the idea of what's sometimes known as rule-based making - with restrictions in place, suddenly it's easier to be free.
This month it's been about drawing with ink in various ways, for the 100 Days Project I created my own set of rules, and there are always new challenges popping up on the internet to be inspired by. For me, fast drawing is good drawing! Stops me from over-analysing (or staring vacantly into space), and gets me into a daily making habit that's just for fun.
