Purchase your preferred glow-in-the-dark equipment. You can choose from paints, powders and markers. There are both professional and hobbyist options available.
Create your artwork using stencils or by tracing the design you would like to create. You can also draw using a free-hand technique and just create whatever comes to you. Using pencil will make it possible for you to erase any mistakes and edit your work before applying the glow-in-the-dark product.
Apply your glow-in-the-dark paint, powder or markers to your sketched artwork. Color in between the lines to help create a more dramatic effect when you turn off the lights. Filling your canvas with large sections of color will increase the luminosity of your project.
Try making dual images — paintings that appear normal under daylight and then glow like crazy under the black light. The easiest way to do this is to create a regular painting and then outline select images in clear black-light paint. However, creating a piece of artwork entirely with the bright hues of black-light paint that is equally beautiful under ordinary light will really stretch your creativity.
