With these two circus characters, I have finished my second set of doodles for the Index Card-a-Day Challenge (ICAD.) While I am admittedly only 12 days into this event (I typically tire of daily challenges around Day 30), I am loving working on these 3 by 5-inch "canvases."
My main trick for staying current? I sketch out (and sometimes even outline) the next day's card once I finish the coloring and shading of the day's illustration. That way, if I wake up feeling poorly, all the "thinking" work is already done and I can just relax. People who are collaging their cards could gather up a few bits for the next day's card or color the background in advance. I suppose it is cheating a bit but let's face it: we're not on the ball every day and life has a nasty habit of getting in the way. If you already have a small jumpstart on the day's card, you're more likely to be able to finish it up once you tackle the suddenly sick family member, the self-replicating laundry pile or the "Oops! There It Is!" appointment that appears on your calendar.
Another important thing to remember is that if you fall behind...DON'T GIVE UP! Take a day off (in addition to the one(s) you missed) and then if you still feel drawn to the challenge after a breather, pick it back up again the following day. Adjust the parameters of the challenge to make it work for you. Maybe you can only manage 5 cards a week. Maybe drawing every day is too draining if you are more comfortable with collage (or vice versa.) Daily art doesn't have to equal a specific number of pieces at the end of the specified time frame.
Anyhoo, here's the next prompt I'm using (beginning June 15 and running through the 20th): "The Fair Folk." I think there's some gnome love on the horizon...
