An interesting male version of the eyeglass brooch could be a
typical Pen and Pencil 'envelope' that is sold for shirt pockets.
The open end could hold one pair of glasses while the overhang
which falls in the front of the pocket could be fashioned with
another metal circle for the second pair of glasses. >>>
Thanks for the suggestions, both on and off list. There are some
interesting ideas although the majority seem to be like the above and
lean towards a 'pocket insert'. I will probably have a try at making
something like a simple pin-on loop (or multiple loop for more than
one pair of specs) though as I can see a 'pocket insert' type just
falling out as I bend over to pick things up off the floor.
