I was talking about the way I'm using line with Ian the other day. The issue with line in my current work is I essentially use the same type of line for everything in my work. This is because I like my natural sketchy line as I think it makes work more interesting and is different to the usual type of line you see in most art. There are some problems with it though and trying to get a difference between the figure and the building in my work is one of them. Ian suggested I look at Patrick Caulfield as an example of someone who uses a completely different kind of line, solid, definite and straight. I would have a lot of trouble drawing a line like this usually as I have shaky hands that make it hard to draw a continuous solid line and keep control (it does give me my natural drawing style which I prefer though). This means to get lines like Caulfield's (or maps which we also looked at the use of line in) I'll have to use a ruler. If I do this for the building on the inside but draw the people free hand then hopefully that should give a big enough difference in line.
