I used to do Gallery Glass painted stain glass windows. My goal was to make it look as close as possible to real cut stained glass. I haven't done any in a long time, but here are some photos of some of the ones I've done in the past.
I just moved my home office into a nice large room and plan to make it a Cincinnati Reds themed decor. I just finished the design to make the window on one wall (facing the neighbor's house) into a Reds stained glass window. I've posted a mock up of how it will look.
