Fellow artist Licia asked me, "Marilyn, what is your best advice for "artist's block" when it hits? Do you force yourself at those times to sit and draw no matter what?"
Yep, sit down and start drawing. But start small, draw tiny, tiny little doodles that are really crappy. :-)
Draw twenty circles or boxes on a page and then turn them into something, faces, animals, houses. I find when I am blocked it is because I have a perfect beautiful picture in my head and not the skills for getting it on paper.
Another way to get jumpstarted it to try new things, new pencils, paints, stamps, pens. Feel free to explore. Try inking with a brush instead of a pen.
If you are totally stuck, just practice your lettering. Anything that gets your pencil or pen moving is good.
I have a million tricks for getting to the drawing. Mostly because it's hard for me. Putting that first mark on paper or starting "a proper drawing" is not something I come by easily.
But the trick is to just show up at the page and let yourself play.
