I love your greenhouse - the model is cute too. I'm in Arizona and would like to build one of these out back, though it might not be practical for my climate unless I open the windows. I'm curious about how you attach the glass to the metal, and where a person could buy a metal framework designed for glass installation. Have you essentially soldered the glass in, as in stained-glass windows? I suppose a wood frame could also be created with glass panels if you layered strips of wood over the edges of the glass.
