So I have been playing the last few days with my Copic Markers. They are really wonderful. Copics are an alcohol based marker. When they are used with the right ink and paper they look like watercolors. What is really wonderful is there is very little streaking. I bought mine from a great online store called Period Style. They had great customer service and threw in a couple of freebies with my order. Of course I am already addicted to these markers and see lots of holes in my collection. I have very few reds and greens. I have alot more to learn about these markers and I also have to figure out how to incorporate them into my collage style.
