Illustrator and workshop presenter extraordinaire, Kelly Light, shared this exercise at the 2012 New England SCBWI conference. Sorry to say, I wasn't there. But, I found out about this fun little challenge that Kelly introduced in her workshop and had to give it a try. You can get the scoop about how this works straight from Kelly by clicking here. Fun stuff! Go for it!
