Recently did 8 stained glass windows for a Methodist church. I have taught stained glass courses in a private acadmy as well in my home. I will be 83 this year. I stumbled upon a web site that had viedos on glass painting. I want to learn more and do some glass painting myself. My wife and I lived in Michigan for many, many years until I retired as an Elementary School Principal. We now live in the Rio Grande Valley of Texas about 8 miles from the Mexican boarder. You are never too old to learn something new.
