Copic Markers for Card Makers
Why do card makers use copic markers?
Card makers like copic markers for creating dimension through shading of their hand-stamped images.
What are copic markers?
Illustrators and other artists have long considered copic markers as the best markers. 
They come in over 300 colors, are non-toxic, acid free and mix well with other media. Copic markers are doubled-ended. To cover larger areas, you’ll use the broad
nib.
For detailed work, you’ll use the fine nib. These qualities make them well suited towards making handmade cards.
How to create dimension with copic markers
What are two keys to successfully creating dimension in your card projects with copic markers? The first key is where you apply it. The second key is how you apply it.
Where
You’ll create dimension by applying additional colors over the base color. Your decision as to where to apply the additional colors will be impacted by two factors. The first factor is the stamp you chose. The second factor is where you decide the light source is. If you chose a stamp that is a simple line stamp then you will have to make all the decisions regarding shading/dimension. If you chose a more complex stamp (one that includes shading), then you can take your cue from it regarding the light source.
How
When coloring in an area of your stamped image, use multiple, overlapping strokes to darken an area of color. To seamless blend colors, apply the second color or stroke while the first stroke is still wet.The underneath layer will show through if you allow your color to dry before adding another layer.
What you should buy
Ideally you should have three shades of each color—light, medium, and dark. Or, you could go with a light, a dark and a blender pen. See the image below to see what a blender pen looks like. A blender pen lacks pigment which makes it possible to pick up some of the color you applied. If you choose the second option, then you will create the middle value by applying the blender pen to the dark ink.
