How do you capture a day? In hours? In moments? The premise of the Hour by Hour sketch challenge is to put pen to paper every hour of a single day on one journal page, with no sketch taking more than five minutes. I introduced this challenge during a week of teaching at the Hog Island Audubon Camp, where the days are busy and intense. The challenge forces you to work fast and loose, while helping you capture small things that together convey a sense of the day. It’s a good challenge to try when traveling or when you are too busy to take time for a longer sketch. But it’s also a worthwhile exercise if you want to practice being less fussy with your sketching.
