Gamsol Odorless Mineral Spirits
Absolutely the best blending medium for colored pencils and a perennial Inky favorite! Artist-grade odorless mineral spirits packaged in a convenient, sponge-top dabber bottle. This "magical" liquid results in a pretty, almost watercolor-like look since it essentially melts the pencil lines and erases their grainy appearance.
Simply color in your stamped image with colored pencils, and apply Gamsol using the blending stumps (sold separately). (Note: This technique is made for regular colored pencils, not watercolor pencils.)
