A Halloween shadowbox: a purchased shadow box from Hobby Lobby. Spray paint it black. Remember to slide the glass out first. "Wallpaper" the inside. Tie a ribbon around the glass and stamp a spider web on the glass with Stazon ink. Create a vignette using your QK dies. Stacking foam dots will create different depths to which to adhere your elements.
Once the glass is back in place, attach a metal embellishment and a spider to the front!
