My next move was to make cut-out outlines for the 'play objects'. It sounds absurd, but I couldn't think of any other way to do them than by hand, (of course I'm sure someone could have advised me how to do it on photoshop or illustrator!) but I'm happy with the drawing-like effect that it retained. The one drawback was that the lines weren't exactly equally spaced or the same size when once I'd scaled them up or down on photoshop. But sadly there wasn't time to change that before the deadline.
