Things You'll Need
You can make anything look like stained glass easily with the proper paints. You can paint directly on most nonporous surfaces with liquid leading and glass paints to create faux designs quickly and with little effort. Liquid leading is available in a tube and is sold at hobby stores that carry stained glass supplies. Windows, glass inside picture frames and metal canisters are just a few of the options for your faux stained glass project.
Draw, print or photocopy your design. Stained glass patterns are available at Free Stained Glass Patterns (see Resources). You can also draw a simple pattern yourself; look through children's coloring books for inspiration.
Lay your pattern under the item you are painting if it is clear. If the item isn't clear, you will need to freehand draw it on the item with a narrow-tip permanent marker.
Trace over the permanent marker lines or the black lines of the pattern onto the item with the liquid leading. Keep the lines as even as possible. Allow the leading to dry completely, approximately one hour.
Paint in the empty spaces between the black lines with glass paints in the colors of your choice. A narrow-tip paintbrush will make it easier to get into tight corners. Allow the paint to dry overnight.
Paint your stained glass design on clear contact paper, and adhere it to whatever surface you desire.
Wear gloves when using liquid leading.
