Copics! I love my copic markers. They're great alcohol markers, but they have a big draw back....PRICE! Copics are quite expensive and keep going up do to importing and the USD being low to the YEN. You could get the Ciao as they are cheaper, or you could get Prismacolor alcohol markers. The key to blending is really having multiple shades of one color and blending: LIGHT-MED-DARK-MED-LIGHT. You know, if you're not sure what to do you can get a few alcohol markers and try them. You could get Ultra-Fine Bics, Gina K uses them sometimes. Gina K: Alcohol Markers on a Budget.
I hope this helps you.
