crave: To need urgently; require
As I am on the final finish of this current commission, my hands simply CRAVE to sketch something, anything that isn't remotely related to this children's book. Sometimes it's healthy to take a break, or so I rationalized. I pulled out a fresh piece of watercolor paper and sharpened my brand new Blackwing pencil and began a sketch of one of my sons. He's currently out of state and I only hear from him sporadically. Somehow, I felt closer to him with each pencil stroke.
