Colored pencils are great in an art journal. With just a few of the right colors you can get a lot of colors. Layering is easy with GOOD colored pencils. Though I've included a video with crayola colored pencils, I do not recomend them. They will only leave you frustrated. Get a 12 pack of colors in a good brand.
