My last Early Music Shop carrier bag has just given up.
I got one in July 07 when I bought my treble. I then got another one in Nov 07 at the early music festival. One went in to service as 'the carrier bag that lives in my handbag', the other became my work-clothes bag for when cycling to/from work.
And now they have both given up

I suspect that means I need to go shopping

(In case you are interested, the carrier in my handbag is now Lindisfarne Mead, and my cycling bag is appropriately Ben Hayward Cycles [Cambridge]. I went through our drawer of nice carriers, and they were the best I could find...)
