I have always been drawn to windows with diamond/crosshatched muntins. There is just something so cozy and cottagey about them. When we get around to replacing the old, non-energy efficient windows in our house, I'd love to keep things contextual and old-timey (I know I use this phrase a lot)! Maybe something like one of these beauties for the kitchen or bathroom windows. I don't even know how much they cost... Probably a lot, but they sure are lovely.
And perhaps, if diamond muntins are too much of an expense for windows, we could add it to the kitchen cabinets... A girl can dream!
