Well, truthfully: it's way too expensive and energy-wasteful to lit the fireplace all over the place. I know my grandpa, when he was a kid, used to warm up couple of bricks, and bring those into the bedroom before going to bed. (hot water bottle works magic, as well)The bedroom fire place I don't think was ever properly lit.
Exciting to plan
The blue nursery
This makes me think of that tune popular in the 30's entitled " my blue heaven"
