These little fellows are part of a new eruption of ideas that came about for no apparent reason. Sometimes I think about what I'm going to sketch and sometimes the pics just spontaneously leak onto the paper. They are a bit like dreams as well. Often people can link a dream to an event that happened recently, but at times the dream seems unrelated to anything in the person's life.
And in a like way, sketches can be the result of something recently seen, or an idea I might be working on. Other times, they kind of release themselves from the tip of the pen, and I nearly always find this sort more endearing.
