I knew! Charlie O'Shields, owner of the Doodlewash site and host of WWM also has a bi-weekly podcast called Sketching Stuff. His watercolour/sketching practice is just 15 minutes a day every day and he focuses on one subject; I really like his sketches and the concept seems doable. His podcast is somewhat rambling thoughts on a variety of subjects which he always brings back to watercolouring, and I find his engaging almost childlike delight in things very uplifting and motivational. I looked at the prompts this month and I'll admit some of them intimidate me, not that I planned to take on the challenge anyway as I've already got enough balls in the air right now. But if any of you join in, please share here.
