Have you thought of trying to talk someone into making you a crazy quilt made from scraps from stained glass making? I'm considering doing that, or doing it myself!! I have 2 front room windows that face South, which also face a blank wall of the neighbor's garage. I've been wondering about that for a long time.
In my home town of Milton, WV is a lovely glass plant, Blenko, which used to have a pile of glass bits that they scissored off the lovely glass objects they make there. Other places don't usually re melt their glass and might want to get rid of the tiny pieces they cut off a standard pattern.
Or you might want to try some glass paint. Ever done that? I may go that route if the stained glass is out of sight, money wise. Or I'll keep going to yard sales and flea markets, gathering bright colored flat glass vases, etc, for use in such windows.
