How do you keep them from falling off your shoulder? If you are pushing a pram, do you have to constantly hoik it up? I hate carrying them in my elbow, and I like to have hands free.
I have never got on with them but feel that I should. Of a certain age and feeling a bit like the rucksack look is not a good one! Also, what do you do if you need to carry A4 sized papers? Do you then have a separate bag?
Please explain practicalities and allure.
