Is there some that you draw repeatedly? Doodle over and over? Lately - you may have noticed ;), stones have appeared whenever I hold a pen. It is the heart of the stone that I'm seeking. Inspiration came unexpectedly (you can read this post) and hearts began appearing.
Here is a fun exercise that you may want to try in your sketchbook. Sit quietly with your book and pen and then close your eyes and begin to draw hearts. Hearts are a simple, familiar shape. You've drawn them over and over. Hearts are imperfect, aren't they? So your drawings will be as well.
I opened my eyes from time to time while drawing to get a bearing on the page. My page full o'hearts sat a bit and then words began to form as to what kind of heart it was or what that particular heart meant to me.
If you turn a stone around a bit and you can find the heart.
I think the stone of a heart is soft and warm.
It was fun to rummage through my stone collection, looking for hearts.
