Polish craftwork is fascinating: wood craving and hand-woven rugs come mostly from the Zakopane region of the Carpathians Mountains. Other souvenirs include glass, hand-woven baskets, paper cut-outs as well as pottery and cut lead glass. One of the most common souvenirs is jewelry of amber from Baltic Sea. (Ancient Roman merchants used to come here to get it and the Cesar throne was richly amber encrusted). Each individual piece of amber can be fashioned into a pendant, ring, bracelet, or earrings. Most highly prized is a piece of amber with a prehistoric insect preserved inside, though it is a rare find. Poland is also known for its silver jewelry, which is sometimes combined with amber to create uniquely Polish pieces of art jewelry.


Poles are known for their hospitality and appreciation of good food. Polish meals offer a wide selection of delicacies ranging from fresh game in season to Baltic herring. Red beetroot soup (borsch) is unique. Well known are Polish smoked sausage (kiełbasa) and stuffed cabbage (gołąbki). Dumplings (pierogi) come stuffed with meat or cottage cheese and potatoes, or blueberries, or sauerkraut and mushrooms. 'Bigos' is a stew made of sauerkraut, meat and mushrooms, while roast duck comes stuffed with apples. For dessert, try pastries with poppy seeds or, perhaps, a Polish donut filled with preserved fruit (pączek).
