Plain pillow (bought or made)
Stencil on cardstock or acetate
Print the stencil on cardstock or acetate and cut out the image. To save yourself some time and frustration leave out the tiny bits like the shadows in the background or the details in the image. Also, omit anything you can paint freehand later, like the shadows in the hair or the outline of a hand, as well as most of the facial feature.
Spray the glue on the back of the stencil, making sure you're in a well ventilated area.
Once you have painted the main image, remove the stencil and freehand the details you haven't cut out of the stencil earlier.
