The final medium I want to introduce you to is acrylic paint. I’m sure acrylic needs little explanation because most of us have used it since preschool. Acrylic is a versatile medium that can cover large areas as well as provide detail. It is quick drying and comes in every color you can imagine. Acrylic is a great way to add color to your Zentangle art.
My tip with acrylic is to use a fluid acrylic; heavier-bodied acrylics can become arduous quickly with Zentangle, especially if you are working on a small scale or are looking for fine details. Golden Fluid Acrylics are artist-grade paints that work well, but also look for craft acrylics like Claudine Hellmuth’s Studio line, especially in the small squeeze bottles. These allow you to control your output. I use both types, and there are many great brands out there for you to try.
