Every drawing is in a constant state of working and re-working. Iteration is both a quick way of expressing how I work on a sketch – that is the daily act of sketching, as well as the approach I have working from one drawing to another.
There may be a sketch with which I am totally unsatisfied, something went awry half-way through (I sometimes like the expression pear-shaped) and the drawing just needs to be given up. But rather than totally abandoning it to some folded over page of a sketchbook, I instead look to it as a source to deconstruct and harvest components from for the next drawing.
Often that means cutting out components of the older drawing – some working corner of an image with which I see something I like or something workable – and gluing them to a new page. This forms the seed or the germ from which the new drawing can begin to take shape. From there the work begins again. The drawing takes off, and the process consumes and re-imagines the role of the old part – finding a place for it in the new machine. From one iteration to the next, slowly slinking towards the image I have in my mind, and then on to the next image to come to mind.
