Tsukineko"s Ink Potion number 9 is a blending solution for use with all water-based inks. A myriad of uses can begin with the very basic: dip a Fantastix (or a paint brush or other applicator) into Ink Potion number 9 to blend watercolor pencils or watercolor crayons. Spray Ink Potion number 9 onto an inked stamp for water-color look when stamped. Also, try this technique: spray Ink Potion number 9 onto glossy cardstock. Then drip dye ink onto that area. Then, spray again to encourage migration. Another idea: add ink from an inker into the bottle of Ink Potion number 9 and you"ve just created a custom color background spray. Why not blend two or more colors with Ink Potion number 9 for an even more unique spray? Paper friendly, this solution encourages paper to remain flat as it dries; also reduces "pilling" that occurs with use with water. Offered in a 2-Ounce spray bottle. Also available in 8-ounce refill and 8-ml spritzer bottle.
