Select stained glass paints designed to mimic the shimmer and semi-transparent beauty of stained glass windows. Paint directly on your windows or create a stained glass panel or sun catcher. Imitate the leading in real stained glass with self-adhesive lead strips or liquid leading that you can squeeze on like glue. You can find patterns online or in your local craft store that you can trace onto the glass, apply the leading over the trace lines and then fill in with stained glass paint.

Paint designs onto the outside face of a glass vase, frame, plate or anything you like with paint made specifically for glass. Glass paints are designed to set with heat, so you first paint your design, and then bake the painted object in the oven at a low temperature. Glass paint is more translucent than regular acrylic paint so more light gets through. It's not necessary to bake set glass paint; you can paint your windows with glass paint and let the sun bake it in naturally.

Hold the vase, jar, clear glass ornament or anything else you'd like to swirl paint tilted at a 45 degree angle. Squirt a small amount of acrylic craft paint onto the lip of your glass container so that it can run down inside the glass along the sides. Move the glass container slowly back and forth, twirl it around so that the paint will swirl on the inside face of the glass. Add another color and swirl it the same way. Alternate swirling the different colors until the inside face of the glass is covered with paint.
