I've haven't thought of any good ideas recently. I don't know why this is. I did try out some moss grafiti but it didn't work because of the weather.
On reflection, I don't think moss grafiti is the route I should be going down because it's already been done and I don't feel I have anything new to do with it.
Having experimented with real materials I want to go back to thinking about drawing.
Also, this blog has lots of other people's thoughts on drawing, which should help me form my own opinions on it. I have no problem with other people drawing, but I don't really like the activity myself.
