I love the fact that Anderson's mug is a rusty old tin one. Although I think Mycroft should have a gilt-edged Royal Doulton teacup. - I like how this fandom doesn't even think the the sheer idea of comparing characters to mugs is strange.
Recently I've found myself drawn to steel framed windows. Sort of old world European, or modern industrial look. I'd like the entire sunroom to be constructed of this style windows. Also the front entrance and certain interior walls and doors.
