Hostility? What hostility?
If you had just invented rot-gut wine, by combining a little alcohol and grape juice, would you try to hawk it on a fine wine site??
I'm not in the least hostile. I just asked why you'd be here on a stained glass site, peddling an artificial stained glass product.
I can only conclude that you are doing it to attract the compliments of people like Dennis, 'cause it's sure unlikely that you're going to get anything positive.
