 What's the best tool to make ink monsters with? Well, I use a variety of Indian ink, acrylic ink and watercolor and different watercolor brushes for it. Most of the paper is regular student grade paper in 200 grams thickness or so. If you don't want to use a lot of money, then buying a pencil color brush is great. I've used this brush more than any other in my life. But in reality, the best tool is whatever tool you have at hand. Like, here is a ink monster that I did with my kids markers. If you say to yourself that you want to start drawing, but you don't have the tools, then you're probably just pro-crust- Blah! Pro-crust- didn't- Pro-crust-ring blah. Uh, postponing things. So, in other words, the best tool is often the closest tool.
