How do I insulate the windows of my old house?

We live in an old house. Some windows are painted shut (some even nailed shut, i think). When I go over to open or close the blinds I can literally feel the cool air flowing in and all I think about is the heating bill $$$$ this winter. The same is true of the fireplace... we have not been able to afford fixing the inside chimney bricks yet. Whats a good way to cover the opening... right now I'm using a blanket wrapped around the metal spark guard.... helps some bjut not enough.

    What works best and looks great too are themalnlined drapery. Best window insulator around , works in summer too.

    Until you can pry off the window frames to insert more insulation, I'd follow Kelli's recommendation and purchase 2.5 or triple width draperies with thermal liners. The more folds, the better the insulation. Avoid cotton fabrics if possible, as they lack insulative properties. If you can feel cold air at floor level and you have the option, purchase draperies sufficiently long as to be able to "puddle" them at the bottom. They will drag on your floor, but can be turned under to further insulate from cold air. These draperies can always be held open during the day with "tie backs".

    If possible, tilt your blinds to permit maximum sun entry during daylight hours, to add free heat gain to these rooms.
