I refer to mine as either "my quilting studio" or "my quilting room" or, at times, just "my room." My husband on the other hand likes to call it the bat cave because he can just see my mother and me (the two "old bats") in there drinking wine and talking. (He thinks he's so funny!! LOL) Actually, he is a sweetheart...he enclosed our entire three car garage for me and it is one awesome room definitely deserving of the name studio.
GagaSmith: I refer to my longarm as my Corvette. My husband likes (and collects) C-3 Corvettes.
