Ok, I have a hinge question. I'm making a large Military Retirement shadow box (25 X 35) with a cabinet door style front. What type of hinge should I use? I really want to hide the hinge, but a Blum style hinge is too big for the door frame. I thought of a piano hinge, but not sure how much of it I can hide. There's also the Newbie thing here as I've only installed door hinges before, so I'm not even sure how to install a piano hinge. Any suggestions would be appreciated. Thanks.
