The sack is today most commonly known to be closely linked to the traveling salesman, ‘knallar’, who was traveling around mid Sweden selling their merchandise since the 16th century, the merchandise was usually carried in a shoulder bag.
The word ‘Fässing‘ derives from the unique dialect (Månsing), used by Knallarna, and means approximately stuffed sack. Different spelling; fussing (1587), fässäng, fessäng (1749-1833), fästing (1772-1851). Some areas used the word fässing, or halm-fässing, as the word for a mattress (a bag stuffed with hay). Today most historical interested Swedes use fässing as the word for the shoulder bag, a spelling first seen around 1779.
The Swedish king , Gustavo II Adolf, decided that knallarna, the traveling salesmen, should be controlled (and, you know, actually pay tax), which is why the town of of Borås was founded 1621. Today the city has a high reputation in the Swedish textile industry, and the Borås Museum has a focus on the textile preservation, with many interesting exhibition about textile history. A couple of years back the museum made an exhibition about the history of Knallarna, and as a part of the reconstruction, they made a fässing;
