People looking to learn Stained Glass?

[EricR]

Hi, I was wondering how big the market is for stained glass services.  Also, is there alot of people looking to learn how to do stained glass?  I see alot of stained glass shops where a major part of there buisness seems to be teaching people how to do it.  

For the people that have local learning shops, do you get alot of students?
