Recently came across another old rural name for lunch: ‘Baggins’ (baggings) - delivered to field workers by their wives/children, in tightly woven flour sacks, of the smaller variety; which were relatively narrow, compared to their length. Perhaps the origin of R.R.Tolkien's ‘Bilbo Baggins’ ???
Seemingly, these white(ish) flower sacks were also much prized as single leg ‘knickers’ - each attached to a cotton strap which went around the waist, leaving a gap, fore and aft, for bodily functions. They were commonly, or vulgarly, known as ‘Free Traders’ - a reference to a type of economics which allowed a trader to do anything they wanted, without having to pay tariffs. I suppose the analogy meant that wearing ‘Free Trader’ allowed the wearer certain ‘freedoms’ without recourse to taking them off.
I was told the above, by an older friend, whose grandmother/great grandmother used the term. Further, before converting the flour bags to knickers, they had to be washed, and rollered several times, to soften the fibres. One method was to anchor them with a stone, and leave them in a stream for several days (?) before beginning the washing process. It all sounds a tad ‘itchy’ - but the absence of a ‘gusset’ must have made them rather more bearable. Truly a case of make-do and mend!
