I really like sketching this way. Too often I get wound up about having to draw in the "right" atmosphere. All that does is create opportunities to not draw. Approaching it casually means there's no stress to make a perfect drawing. It's just a fun time scribbling. Whatever happens on the page, good or bad, is ok.
Speaking of ok, the baby checked out great. All is good, and she's on track to arrive next month (yikes)!
