I’m drawing our sparrow nestbox for a forthcoming article in The Dalesman and, rather than draw it from life or trace it from a photograph, I’m trying freehand perspective. I didn’t draw an horizon line or plot vanishing points, I just drew as near to the way they appear in a photograph.
Having used ruler and set square for the pencil, I’ll use my usual freehand fountain pen for the drawing itself, so hopefully it will looked relaxed but plausible.
