I have recently gotten into coloring digital images with Copic markers. These markers are alcohol base markers and for anyone who loves to color, you should totally check out these markers! I have always loved coloring but these markers changed my life. You can buy this markers at your local Hobby Lobby (don't forget your coupon).
I only do the card building and coloring, I DON'T draw the images. I get those from a shop online called Saturated Canary.
