Wow, I've thought of trying this someday, too. If you do attempt it, please let us know how it works! I think it would be so kewl to view the girls in this way. :applause:Hey how about this.
A hole cut in the side of a standard hive. Fasten a glass piece from the inside. Then add a hinged door on the outside of the glass panel. You could have a looking hole. Or I guess a window in the side of the hive with a closable door over it???
