I have a nasty feeling that either things are tight and uncomfortable, or loose and fall off. Or all of them at once. I feel that surely someone ought to sell some sort of adjustable metal close clip that sits on the outside and holds them in place comfortable. Youngest Sister said that one suggestion she'd seen was sewing a button to the brige that your glasses could rest on.

I have got a jersey one I purchased for £2.99 in Holland and Barrett, which is quite decent, and am tempted to have a go with some rather magenta fabric I have hanging around.
