Coloring with Copics can be quite intimidating to a beginner. I find what is most intimidating is the neutral color palette (the browns and skin tones) Here are my tips when color with Copics:
Remember to press lightly when using these markers. you don't need to soak the paper to get good color results. You only want to see a little bit of color coming thru the back (depending on the paper you are using.) Over soaking your paper will result in bleeding outside your stamped image.
Remember to practice with your copics! Practice makes perfect!
