I know this is simple and i should really know this by now, but i installed an inset cabinet door and it doesn't want to stay shut... I put the hinge mortise on the door and no mortise on the frame. Is this happening because the mortise is too deep, too shallow, or supposed to be on the frame instead of door, or not supposed to have a mortise at all. thank you guys you have helped me so much, i plan to start tithing to this site, hehe
