How 'bout this. For inset doors, you don't need hinges. A cabinet will usually have either the bottom edge or the top edge that can't be seen easily. This method is very simple. The door pivots on two small pieces of hardware.
As an example, an upper cabinet in a kitchen. Drill out a hole in the top near the front approximately 1/8", and a pilot hole in the top edge of the door. Insert a screw through the top of the cabinet, then a nylon washer or steel, and into the top of the door.
The bottom of the install consists of inserting a pop rivet in the bottom edge of the door at the same plane as the screw at the top. Drill a small hole in the floor of the cabinet for the pop rivet nose to be inserted through a washer. The nail part of the pop rivet may have to get snipped a bit shorter.
To install, set the door with the pop rivet through a washer into the floor of the cabinet. Then, at the top, place a washer over the hole on the top of the door and insert screw. The screw should be snug to the cabinet, but not tight enough to impair rotation of the door. This setup for an upper cabinet is reversed to do a base cabinet, wherein the pop rivet goes into the top of the door, and the screw is at the bottom.
Why you ask? Well, you don't see the screw on the bottom of the base cabinet or on top of the upper cabinet. I've done this type of configuration many times, and the screw does not wallow out the hole...believe it or not. This works if you have access to the underside of the base cabinet and the top of the upper cabinet.
Talk about being subdued...nothing shows.
