Do it yourself stenciling on nylon duffel bag?

To stencil a design on a nylon duffel bag, start by cleaning the surface to ensure proper adhesion. Use a fabric spray paint or permanent fabric markers, as they are designed to adhere to nylon. Secure your stencil in place with painter's tape, then apply the paint evenly, taking care to avoid bleeding under the stencil. Allow it to dry completely before using the bag to ensure the design holds up well.
