Thankfully, D has a little bit of know-how when dealing with practical fixes around the house. (Thankfully he also knows when he's over his head and needs to call a professional!) D had some glass cut-to-order at the local Mom-n-Pop hardware store. Then he put the window in and has given it its first coat of paint. We had the windows painted over when the house was painted. We think it makes the garage look less like it's from the 1960's (which it is). An added bonus: you can't see all the junk we store in the garage. I have trouble even walking through it's so full of ... stuff. Didn't D do a good job? G owes him $5 now. He got off lucky. It needs only one more coat of paint and then we're done.
