I have a tiny log cabin that gets very little light. There are no windows at all on the gable ends near the roofline. I would love to put hexagonal windows at each of the ends of the cabin, but I really can't afford them. Has anyone tried installing small square windows diagonally? I know it would be tricky as far as the headers go, but what's the difference between framing a diamond-shaped window, versus a hex, really? I can see that it would open funny, but would like to know if anyone has tried this?
