To paraphrase Forrest Gump, watercolor is like a box of chocolates--you never know what you're going to get. I think that's why I love it so much. Today, I coated a previously gessoed MDF board with Daniel Smith watercolor ground to see what would happen. It was an interesting experiment but wasn't appealing to me that much until I was nearly finished and gave it a squirt of water here and there. Holy moly! It was just what the painting needed as the water lifted off paint and gave the stream some bubbly action.
