When weatherizing windows is it best to put plastic on the inside or outside of the house?

3M has wonderful kits you can buy that double back tape the plastic to the inside, then literally "shrink wrap" the plastic to the window with a hair dryer!
If you put them on the outsides, be sure and use thick strips of cardboard or thin molding. Wrap the plastic several times around the trim that you choose and staple or tack to the frame. This will keep the plastic from splitting in the wind.
Shower curtains from the dollar tree are a cheap source of plastic for smaller windows, as you can often double up on the thickness.
Also, Walmart has rolls of 60" wide plastic in varying thicknesses, that you roll out how many feet you want the they cut it for you. It's in the craft/fabric section.
Keep in mind that most of your heat loss will go through your windows. But insulation in the attic is even more important, since heat rises. Another thing that will keep your feet warmer and your pocketbook fatter is to block any crawl space vents with the styrofoam blocks. If you can't afford them, block them with wadded fiberglass (gloves!!) insulation, very small packing peanuts in double bags sealed really tight and then block them with a board and a cinderblock.
