This hinge is for an acute angle cabinet: http://www.thehardwarehut.com/catalog-product.php?p_ref=190848 This one is for hinging an inside corner door: http://www.thehardwarehut.com/catalog-product.php?p_ref=190839 The link is to the index page for these special angle hinges at a seller I have used. Blum makes similar stuff, but all of their retailers have infuriatingly complicated webpages/indices to access all that they actually have.

Thank you so much for these ideas and the technical terms ! I wasn't even sure what to google other than 'hinge' which returns a bazillion results, lol. Yes, inboard of the pivot point is the problem I was trying to explain. If I have to overlay the excess not centered to the opening, I will. But that takes my mirror further to the left than I wanted to be (hinge will be on the right). Ideally, the excess would be to the right, on the same side as the hinge, with just a little overlay on the left. When I googled 'overlay partial wrap hinge', I also found these hinges. I think the plate would have to be mounted on the face of the sheetrock, with longer screws that would go thru the sheetrock and screw into the studs, but would these work ??? It looks like they would allow the mirror to have a very large overlay on the right and also the hinge would be hidden. http://www.hardwaresource.com/hinges/cabinet-hinges/blum-european-hinges-grass-european-hinges/blum-compact-33-hinges-and-mounting-plates/blum-compact-33-face-mount-plate http://www.hardwaresource.com/hinges/cabinet-hinges/blum-european-hinges-grass-european-hinges/blum-compact-33-hinges-and-mounting-plates/compact-33-hinges I see the hinge is supposed to be inserted into a drilled out cup. Vice versa, could the face plate be mounted on the mirror, and the hinge cup be drilled into the sheetrock ? Would the hinge still open correctly ? The reason I ask, is because I am not sure what material the frame of the mirror is made from and also if it is deep enough to allow me to drill the cup. Lateral hinges I think would not work, for the same reason as the drawer glides mounted sideways - I don't *think* there would be enough room. We're down at the beach house right now (our last guest broke the side rail on one of the bunk beds and we're here fixing it, no idea what they were doing to break the rail lengthwise all the way from end to end!! kids jumping on the bed I would guess), but I can measure for that idea when we get home tomorrow.

Yes, that brings up some pics that are a match ... thanks! Now, I need to determine the difference between mortised, half mortised and non mortised hinges! These will be for existing built ins in the kitchen with inset doors ... someone must have replaced the originals bc these are shorter than the cut out notch inside the cabinet and they don’t have the decorative ball tip.

My cabinet guys called them knife hinges. I have them on my cabinets.
