Video time! Here's the other sketchbook I'm using at the moment. This ones the neater of the 2 and gradually filling up with patterns and portraits. I prime the pages with blocks of acrylic colour and then draw on them with paint pens. I probably don't need to prime the pages in this one but I find the ink from the pens causes the pages to fall apart in most of my sketchbooks so this is a tactical way around it. It uses up excess paint I've accidentally mixed for other projects too which is an added bonus. Not to mention the obvious block colour background helps make the colours pop. So there's 3 good reasons! It's definitely work in progress.
