I really like the Bic-Markit markers! You can add a copic colorless blender pen and have lots of fun doing texturizing techniques. Here is a card I made with a Bic-Mark-it marker and a colorless blender pen.
Then, like other posters have said, you can fill in with Copics or other Alcohol markers for the lighter or paler shades you need along the way.
For some reason, it won't let me upload a photo. I will try in the next post... Sorry!
