I added a mask over the pumpkins leaving the mask in place over the cat, too, and then created the background with sponged on Distress inks: Brushed Corduroy, Black Soot, Broken China, Faded Jeans. The stars resisted the ink. I added Stardust Stickles to give them sparkle. I also added Stickles to the bat, pumkins, ground and the cat's hat using Black Diamond and Yellow.
Hope your Halloween isn't too scary!
