I wanted an eerie background for what I would expect to find in Harry's backpack, and decided to airbrush two colors together and try it.
Lockhart's Potions and Spells was stamped with Memento Tuxedo Black ink onto white cardstock (Papertrey Ink) cut from Spellbinders Labels Five. I had a mask of this image created earlier (using Eclipse tape) and placed the mask over the stamped image.
With the mask in place, Copic W3 andYG95 were airbrushed - grey first, then the green.
Removed mask to reveal the eerie look. 
Image was colored with Copic markers. Labels Five cut and embossed Licorice cardstock - used foam dimensionals for each layer.
Black pearls are from Ellen; patterned & purple paper is Cosmo Cricket's Haunted kit (name of paper is Haunted Macabre). Card base is Memory Box Paprika. Bippity sentiment is Lockhart Stamp Company. Added Glossy Accents to the crystal ball.
Interior sentiment is from Savvy Stamps. Finished size is 4-1/4" x 5-1/2". Now if I could just brew up a spell to do all the laundry...
