All right, our house is freezing, and it's mainly cause of the windows. We don't have real windows, we have a double sliding glass storm window. Buying windows is very expensive, so I'm looking to build some. Just 2 basic wooden sashes per window, nothing fancy. Anyways, does anyone have some good links for how to do this??? I've been googling for the past 2 hours and haven't found anything that tells me how to do this from scratch, they're all about hanging and buying windows. Thanks, guys!!! BTW, even if this is a difficult task I'm still gonna try it. I'm pretty good at figuring things out, but in this case I don't have something to look at to get an idea. So yeah, just to let everyone know, I'm NOT gonna be discouraged!! I'm dead set convinced to try to build at least one!!!
