I did tons of drawing for the Paper Planes project; not much of it made it into the final drawing, but in a way, all of it did.
I think I spent a whole day chewing my pencil and scribbling. Of course I'd thought about the drawing from the moment I got the brief, and knew exactly what I wanted to do, but I never know how I'm going to make that happen until I start. Or how it's all going to turn out.
Sometimes the same stubborn idea keeps popping into my head, and I have to draw it to get rid of it. Sometimes I have to draw it to see what's wrong with it.
I really really liked the picture of the ghost looming over a small town, but the story didn't have anything to do with the town, alas.
I'm saving the idea of the town, though; it's going to make a very nice stripey repeat pattern for a lino block.
Once I settled on a composition I liked, I drew it up on A3 paper, which took about a day. That evening I looked at it again, hated it, and redrew it, which took about two hours. I used the discarded drawing as a practice piece for the texture of the mountain, and to see whether the flowers stood out well enough on it, which also meant I wasn't too nervous when I started inking the final piece. (Usually the first half an hour of inking is complete rubbish.)
So all in all, a week of solid drawing.
