When painting glass windows, the first step is to choose the right paint. There are many different types of glass, so it’s important to find a paint that will work well with all of them. Next, you’ll need to prepare your window. You’ll need a stretcher bar and a large brush. You’ll also need a small amount of each paint type: white, black, and brown. Once you’ve chosen your paints, take your stretcher bar and place them over the top of your glass window. Then use your brush to spread the paint evenly over the top of the stretcher bar. Finally, use your hand to smooth out any wrinkles or bubbles that may have formed on the surface of the glass.
