I am excited to share several fun and exciting Sharpie coloring techniques that you may never have seen or considered. And of course these techniques work with most any brand of alcohol markers including Copic, Spectrum Noir and Bic.
Great info on using colored pencils - Prismacolour. Using baby oil is a great element and cheaper to blend colors vs the odorless mineral spirit. Just place a cotton ball with some drops of baby oil (not drenched) on a small jar and wet stump to blend.
