Seems like the recommended hinge for a floating mount is the V-hinge whereas anything over-matted is a T-Hinge. Why? My tests tell me a T-hinge is more resistant to problems when the framing is transported or stored by mistake with the art hinges on the sides rather than the top. T-hinges seem just as easy to apply, just have to be positioned lower so they are hidden by the art. I would also say that the v-hinge has a design which tends to encourage gradual movement of the hinge (and artwork) at the bend line as it is much easier to pull away from the board at this point than shear the hinge lengthwise in the case of a T-hinge. Am I missing something??
