Itinerant trading played an important role in the history of the Slovak population's trade and employment. It developed into separate, specific professions, which became important resources for families and individuals, and in rural areas these professions often brought in a higher income than agriculture. Itinerant trading in textiles included linen weaving, lace making, embroidering, and bag-making, as well as bulk buying of old textiles.
Trade in wooden products covered a wide range of goods: agricultural tools, dishes, toys, weaving reeds, and sieves. Doormats, baskets, and pottery were also sold itinerantly, as were lime, charcoal, axle grease, sheet and blown glass, sheet metal, and wire products (tinkering). Agricultural products and food, such as vegetables, fruits, alcohol, woodland fruits, cheese, milk, butter, eggs, crops [?], and edible oil were also sold. Oil making (trading in medicaments) and the selling of saffron played an import role in itinerant trading. There is evidence of some of this type of trading, i.e. oil selling, from the 16th century.
BTW, Matica slovenska is selling a book on tinkering < http://www.vydavatel.sk/sk/historia-33/dejiny-statov-miest-35/drotarstvo-25278.html
