You can use a screw to print a bold piece of fabric, and then hang it up on the wall as a picture. Keep in mind that the screw head should be completely flat, not rounded, for great results. Start by pouring some fabric paint onto a paper plate or palette pad. Roll a foam rubber roller in paint, covering it well. Then roll paint onto the screw head and press the screw head against the fabric. Roll on more paint before each print. It may be smart to print a test piece first.
