I remember baling twine with nostalgia. I don't suppose it is easy to get nowadays as bales not wrapped in polythene are not common. It was used for all sorts of things like holding up your trousers or as a belt round an old coat used for working out on wet days and more commonly nicky tams.
Nicky tams for the uninitiated were tied round your trouser legs just below the knee to raise the hem up a bit out of the mud. The posh ones were leather but the common herd just used baler twine.
I like the "Nicky tams" explanation. In my travels on my Brompton I tend not to wear cycling specific gear but prefer to wear jacket, trousers and shirt, with a v necked pullover if it's chilly. I tend to tuck my trouser legs into my socks which are usually wooly hiking socks, though on occasion I'll wear red or orange socks to match whichever Brompton I'm riding. I find traffic tends to give me a wide berth which is good, but I like the idea of the "Nicky Tams" and may well ad those to my cycling wardrobe 😎
