I also plan on semi-plush carpet. I found an IN-THE-WALL 1500W space heater which fits between the wall studs. And finally I will put a small 1' x 2' stained glass panel on a side wall for nice lighting. Seriously.
So any different ideas for the walls and ceiling? Something rich and warm feeling? Thanks!
PS: The warm room and other telescope room are both 8x10' big.
