So, I have this built in hutch/cabinet in my dining room, it's original to the house that was built in the 50s. I painted it white, and want to replace the hardware on it, to make it look fresh and updated. I'm fine with replacing the knobs and pulls on the drawers, but how do I know what kind of hinges I need? Do I just take the old hinges into Home Depot and hope that a worker there can figure out what size I need? Or is there a way of measuring to determine which replacement hinges are going to work? The hutch as two glass doors on it, each door has two panes of glass, and there are hinges inbetween the two panes of glass, then there are hinges that attach the doors to the side of the hutch, so they fold open like an accordian, kind of... Help! Thanks!
